Abstract
The helmet shell material featuring a gradient in bending is urgently required for the next-generation integrated helmet system. However, achieving a bending gradient design for orthogonal woven composites on a 3D shell surface is a significant challenge. Here, nonorthogonal woven composites at 30°, 45°, and 60° were fabricated, and their bending properties are discussed. Furthermore, their bending properties are compared to those of plain off-axis woven composites, which indicates that the bending linearity trend of nonorthogonal woven composites is evident. Notably, the bending strength of the 30° and 60° nonorthogonal woven composites is 66.9 and 67.4% higher, respectively, than that of the plain off-axis woven composites, and the bending modulus is 169.8 and 196.9% higher, respectively. Finally, a finite element analysis of the bending properties of nonorthogonal woven composites was conducted, and a stress analysis of the inner layers was also conducted. This work paves the way for designing gradient materials for helmet shells.
1 Introduction
Helmet skeleton material is essential personal protective equipment for the human body in aerospace, architectural engineering, sporting event, fire rescue, and explosion-proof filed [1,2,3,4,5,6]. Therefore, people are trying to develop special materials for high-performance helmet shells. Among them, composite materials are favored because of their high stiffness, high strength, light-weight, high-temperature resistance, fatigue resistance, corrosion resistance, vibration reduction, high designability, and a range of other advantages [7,8]. The research of helmet skeleton materials focuses on the design of potential textile structure composites to meet the informatization and functionalization needs of helmets with complex shell structure and multiple functions. However, the helmet shell with complex curvature causes the plain off-axis woven material to wrinkle in the process of helmet body laying [9]. So, the plain off-axis woven materials must be cut to adapt to the complex curved surface of the shell [10,11], which results in stress concentration [12] of the helmet shell and the decline of protective performance. To solve this issue, researchers turned to nonorthogonal woven materials to improve the integrity of the helmet shell and achieve the variable stiffness design in the shell area. The research on woven composites has important engineering and academic value, but it is limited to the weaving process of woven materials. There are few reports on the preparation of nonorthogonal woven fabrics and the mechanical properties of nonorthogonal woven fabric-reinforced composites.
In view of the special use of nonorthogonal woven fabrics in aerospace and weapon equipment, it was mainly focused on the technological design and preparation in the early stage. Dayin [5] first put forward the viewpoint of developing nonorthogonal woven fabrics based on the development of aerospace technology and national defense technology, even the successful development and utilization of high-modulus carbon fiber, but the disadvantages of narrow width, unstable structure, and complex production process were revealed. The special structure and industrial application of nonorthogonal woven fabrics make it develop rapidly in the field of industrial textiles. Based on the complex weaving process constraints of nonorthogonal woven fabrics, Liu et al. [13] fabricated the nonorthogonal woven fabrics on the dobby loom machine and tested its basic properties. The off-axis tensile strength and tear resistance of nonorthogonal woven fabrics are stronger than the orthogonal plain weave fabrics under the same conditions. Due to the special fiber orientation of nonorthogonal woven fabrics, the outer layer used for driving the V-belt can greatly improve the wear resistance and reverse bending fatigue resistance of the belt body. Lvliang et al. [14] developed a wide-angle woven fabric for polyester cotton-blended V-belt. Through many tests, it is found that the polyester cotton-blended fabric has good heat resistance and wear resistance and can overcome problems such as the decline of wear resistance caused by too thick canvas. At present, the main method of producing nonorthogonal woven fabrics is realized through secondary processing. Its production process and production equipment [15,16] are relatively complex, resulting in an increase in production cost. To optimize the production process of nonorthogonal woven fabrics, Yanqin et al. [17] proposed and designed a special rapier loom for wide-angle woven fabric, which makes it form an angle of 120° or 60° with the warp through off-axis weft insertion, which greatly improves the production efficiency of nonorthogonal woven fabrics.
With the continuous expansion of nonorthogonal woven fabrics, the performance of this type of fabric has been widely concerned. Yao et al. [18] not only used the air jet loom to weave the nonorthogonal woven fabrics by using the water jet to guide the weft diagonally but also initially explored the tensile properties of polyester wide-angle woven fabrics. As a result, the tensile properties of the wide-angle fabric that own the 60° warp and weft yarn angle showed that the breaking strength of the fabric was large and the breaking elongation was small when the wide-angle fabric was loaded along the warp direction. Differently, when subjected to the load along the weft direction, the breaking strength and elongation at break of the fabrics are both large. Through research, we come to the conclusion that wide-angle fabrics are better than plain fabrics in terms of mechanical properties and have broad application prospects. Zhang et al. [19] proposed a method of wide-angle fabric preparation with a warp-weft yarn angle of 120° and deeply studied the mechanical properties of this fabric. The results show the elongation at break and the elastic modulus in the warp and weft directions exhibit varying degrees, compared with conventional woven fabrics, indicating that the nonorthogonal woven fabric has excellent strength and deformation characteristics.
Considering the superior mechanical properties of nonorthogonal structure, it has great potential in helmet shell materials. Therefore, 30°, 45°, and 60° nonorthogonal woven composites were prepared and the bending properties of the materials were explored in this work. Ideally, the linear characteristics of this type of composite are evident. Furthermore, the bending characteristics of nonorthogonal woven composites were studied, revealing that both their bending strength and bending modulus were higher than those of the plain off-axis composites. In addition, numerical simulations of the bending properties were carried out by using the finite element software ABAQUS, and the results of the finite element simulations were compared with the experimental results, which is to further carry out the stress analysis of the inner layer in the specimen. Therefore, using a nonorthogonal structure, helmet shell composites with superior bending performance can be prepared. Consequently, the shell material combines excellent bending properties with the gradient design features of the helmet shell. The feasible study proposed in this work could offer a promising strategy for the development of new-generation helmet shell materials with enhanced bending properties and a design oriented toward gradients.
2 Materials and methods
2.1 Materials
The warp and weft yarns of woven fabrics and nonorthogonal woven fabrics were both made of aramid 1414 that was provided by Yantai Tayho Advanced Materials Co., Ltd. The yarn density was 1,100 dtex, single strand, and both warp and weft densities were 110 bunch/(10 cm). The fabrics were prepared at the National Experimental Center for Fabrics of Tiangong University. The Q-301 epoxy resin was supplied by Suzhou Colorless Stone Chemical Co., Ltd. The epoxy resin and its related accelerator are of analytical grade and used without further purification.
2.2 Fabric preparation
The plain off-axis woven fabrics and nonorthogonal woven fabrics are shown in Figure 1. Aramid 1414 filament bundles are used for both warp and weft yarns, and plain off-axis woven fabrics and nonorthogonal woven fabrics are woven on a small sample loom. The nonorthogonal woven fabrics are realized by a special warp edge design, an edge locking design, and a special weft-triggering mechanism design. The warp and weft yarn angle “θ” can be varied from 30° to 150°.

2.3 Composite specimen preparation
Plain off-axis woven composites and nonorthogonal woven composites were prepared using the resin transfer molding (RTM) process. The composite specimens measured 130 mm × 15 mm × 3 mm, in accordance with GB/T 1449-2005 “Bending Performance Test Method for Fiber Reinforced Plastics” (year) [20]. The off-axis woven composite specimens included angles of 0°, 30°, 45°, 60°, and 90°, with the weft direction at 0° and the warp direction at 90°. Correspondingly, the angles of warp and weft yarn include 30°, 45°, and 60° in the nonorthogonal woven composite specimens. Both types of samples are defined through the cutting direction along the weft direction. The cutting schematics of plain and nonorthogonal woven fabrics are given in Figure 2(a) and (b), respectively. Figure 2(a) is the schematic diagram of off-axis cutting of plain off-axis woven specimens. Different angles were divided according to counterclockwise; Figure 2(b) is the schematic diagram of nonorthogonal woven fabrics, where the specimens are cut along the weft direction. The fabric was cut to the size required by the RTM mold for curing and laid into the mold using the 0°-layering method for preparing woven composites via the RTM process. The preparation process is shown in Figure 2(c). The fiber orientation of the formed composites is shown in Figure 2(d) and (e).

2.4 Test methods and devices
The three-point bending test in accordance with the standard GB1449-2005 “fiber-reinforced plastic bending performance test method” for testing, the span-thickness ratio is 32:1, the radius of the indenter and the radius of the support are 5 mm, and the loading speed is 2 mm/min. The Shimadzu AG-250KNE universal material testing machine was used for testing, as shown in Figure 3.

3 Results and discussion
3.1 Bending characteristics analysis
The three-point bending test was performed to study the ultimate bending strength, bending stiffness, and the bending characteristics analysis of the material, which was loaded until the specimen failure. As shown in Figure 4, the bending characteristics are clearly displayed under different off-axis cutting angles 0°, 30°, 45°, 60°, and 90°, respectively. It can be seen that the bending strength–deflection curves of 30°, 45°, and 60° off-axis woven composites show nonlinear trends with the change in off-axis cutting angles. Differently, the 0° and 90° woven composites showed approximately linear trend, which also indicated that the common woven fabrics had the important off-axis effect. The bending strength–deflection curves of 0° and 90° specimens increase approximately linearly until the maximum bending strength, after which there was the clear failure characteristic. The explanation was that the fibers along the axial direction own faster mechanical response when bearing the external load for the 0° and 90° specimens. When the failure load is reached, the fibers fracture or withdraw, which results in a sharp decline. For 30°, 45°, and 60° specimens, the bending strength–deflection curve showed a linear increase in the first stage, and then, the non-linear trend near the failure load happened in the second stage with the large bending deflection and lower bending strength. Due to the similar fiber orientation of warp and weft yarns, the fiber bearing capacity of the composite under external load was similar, which led to the similar bending characteristics of 30° and 60° off-axis cutting specimens. Most surprisingly, the bending strength of 45° off-axis cutting specimens was the smallest, which was completely different from the theoretical value. In this case, the 45° off-axis structure caused the extremely unstable fiber statement, which was highly susceptible to deformation and failure when the composites were subjected to an external load.

Bending strength–deflection curves of plain off-axis woven composites.
Figure 5 shows the bending characteristic curves of nonorthogonal woven composites, which gave the bending characteristics of the composites at 0°, 30°, 45°, 60°, and 90° warp-weft orientation angles, respectively. Obviously, the bending strength–deflection curves of the nonorthogonal woven composites increased linearly with the change of fiber angle, which was highly related to the fiber orientation in the composites. In the preparation process of nonorthogonal woven composites, the fabrics were cut along the weft direction, which made the weft yarn always along the length of the composite, and the warp yarn is the twill yarn. Therefore, when the composites received an external bending load, the twill yarn only affected the bending resistance of the composites at different degrees, but it did not change the bending characteristics of the composites. Although the bending strength changed, its bending characteristics did not change. As shown in Figure 5, the 30° specimen owns the largest bending strength, which was mainly dependent on the largest warp yarn partition force in the length direction; thus, it can be involved in the resistance of the external bending load. Notably, the bending strength of the 45° specimen was the smallest, but the theoretical value of the 45° specimen should be lower than that of the 30° specimen and higher than that of the other specimens. However, this was not the case; the 45° fiber angle caused the instability of the composite structure, which can easily lead to deformation and failure of the composites. Therefore, the bending strength of the composites with the 45° nonorthogonal woven fabric in the experiment was the smallest.

3.2 Bending results and discussion
The comparative results of bending strength of plain off-axis woven and nonorthogonal woven composites with different angles are clearly displayed in Figure 6. The result from Figure 6 pointed out that the bending strengths of 30° and 60° nonorthogonal woven composites were 66.9 and 67.4% higher than those of plain off-axis woven composites, respectively, and even 21.5 and 9.0% higher than those of warp-oriented and weft-oriented woven composites, which showed that the nonorthogonal woven composites owned very good bending performance. The bending strength of 45° plain off-axis woven composites and 45° nonorthogonal woven composites was the smallest, evenly smaller than that of the other composites, which was mainly due to the unstable reinforcement structure that aramid fibers 45° arrangement. In addition, the bending strengths of 30° and 60° plain off-axis woven composites are basically the same, which is mainly due to the fact that the warp and weft orientations of 30° and 60° are basically the same, and thus, their bending strength values are basically the same.

Comparative analysis of bending strength.
The comparative results of the bending modulus of plain off-axis woven and nonorthogonal woven composites with different angles are clearly displayed in Figure 7. Apparently, the bending modulus of 30°, 45°, and 60°nonorthogonal woven composites is 169.8, 134.1, and 196.9% higher than that of plain off-axis woven composites, respectively, while the bending modulus of 30° and 60° nonorthogonal woven composites is 67.0 and 47.1% higher than that of 30° and 60° plain off-axis woven composites, which prominently showed that the nonorthogonal woven composites owned the excellent bending stiffness. This is mainly related to the different warp-weft interweaving angles, which is consistent with the results of the above-bending strength–deflection curve analysis.

Comparative analysis of bending modulus.
The comparative results of bending deflection of plain off-axis woven and nonorthogonal woven composites with different angles are clearly displayed in Figure 8. The maximum bending deflection of nonorthogonal woven composites was smaller than that of plain off-axis woven composites, which is mainly due to the different fiber orientations along the length of the composites. The above analysis showed that the nonorthogonal woven composites have greater bending stiffness and resist bending deformation compared with the twill-cut woven composites.

4 Finite element numerical analysis
4.1 Finite element model
In this work, the bending properties of plain off-axis woven and nonorthogonal woven composites were numerically simulated by using the commercial software ABAQUS 6.13. Considering the nonorthogonal layup of these composites, the internal layers experienced complex and variable forces under external loads. Therefore, the model was configured with all layers in the [010] orientation [21,22]. The basic parameters of the internal layers were defined by setting the real constants, as shown in Table 1. The Hashin failure criterion for the composite damage model was chosen, and the model parameters were determined by defining the material anisotropy parameters. “Rigid Model” that was determined by defining the density, elastic modulus, and Poisson’s ratio was selected for the loading head.

Regarding the bending model, the laminate was placed on two fixed supports with a distance of 96 mm between them; the loading head speed was set at 2 mm/min. The model’s middle part is subjected to a downward displacement. The mesh of the laminate consisted of ordinary shell cells (S4R) using the “Hashin-2D criterion.” The simulation process included the deletion of all failed cells, which was computationally managed using the ABAQUS/Explicit solver, and the results were post-processed. The geometric modeling and boundary conditions are depicted in Figure 9.

4.2 Finite element simulation results of three-point bending test
Three-point bending loading finite element simulations were carried out for plain off-axis woven composites and nonorthogonal woven composites, respectively, for a total of 0° (weft), 30°, 45°, 60°, and 90° (warp) of plain off-axis woven composites and 0° (weft), 30°, 45°, 60°, and 90° (warp) of nonorthogonal woven composites. A total of ten types of specimens were planned to be used to examine their bending characteristics and bending stress distribution. The finite element simulation results were compared with the experimental results. The finite element simulation results were compared with experimental data. The bending modulus comparison between these simulations and tests is detailed in Table 2. Table 2 indicates a significant discrepancy for the 0° (weft) and 90° (warp) woven composites, whereas the nonorthogonal woven composites showed good agreement between simulation and experiment. The primary reason is that while the simulation process accounted for the overall performance of individual plies in the laminate, it did not fully consider the coupling effects within the plies, excluding axial stress, due to the significant deformation of the fibers. Therefore, a very large error had been generated for the plain off-axis woven composite.

Figures 10–13 show the stress distribution in nonorthogonal woven composites when subjected to an external bending load, with the diagram illustrating the stress from the compression surface to the tension surface. The stress situations of each layer in the composites were shown clearly through the stress distribution diagram. Similarly, 30°, 45°, and 60° nonorthogonal woven composites owned a similar stress distribution state with the 0° and 90° woven composites, which indicated that 30°, 45°, and 60° nonorthogonal woven composites owned the basic characteristics compared with laminated composites. The stress states of the corresponding layers are basically the same, and there was no obvious coupling effect between layers. Even, the first five layers mainly bear compressive stress and the last five layers mainly bear tensile stress from the compression surface to the tension surface. The stress distribution diagram clearly reflects the stress distribution of the composites under external load and provides data support for the internal stress of the composites under external load.

5 Conclusions
In this work, 30°, 45°, and 60° nonorthogonal woven composites were successfully prepared and the bending characteristics of the materials were investigated. Through the analysis of test results, their linear characteristics were obvious. The bending characteristics of nonorthogonal woven composites were compared with those of plain off-axis woven composites, revealing that both the bending strength and modulus of the nonorthogonal composites were higher. In detail, the bending strengths of 30° and 60° nonorthogonal woven composites were much higher than those of plain off-axis woven composites by 66.9 and 67.4%, and the bending modulus was higher by 169.8 and 196.9%, respectively, which showed that the nonorthogonal woven composites owned good bending properties. In addition, an in-depth finite element analysis of the bending performance of nonorthogonal woven composites was conducted, followed by a detailed stress analysis of the internal plies of the specimens. The numerical results were comparable and, in some aspects, superior to the experimental outcomes. The feasibility study and the remarkable results presented in this article offer a promising strategy for developing new-generation helmet shell materials characterized by high bending properties and a gradient-based design.
