6. Aggrandized flexural properties of assorted natural biological materials

Swaroop Gharde
Abstract
The changing scenario in the expeditiously developing industries requires different functionalized materials exhibiting application-oriented mechanical properties. Engineering materials have some limitations with individual materials for a broad range of mechanical properties (impact, fracture). These limitations can be overcome by composite materials, which give the ability to tailor and incorporate the specific functionality in the materials, using specific matrix and reinforcements. Synthetic materials have defied most of the materials in developing high-strength structures and adversely the presence of paradigm materials boasting an ingenious combination of mechanical properties has greatly inspired the scientific community for the advancement functional composite materials. The natural biocomposites such as molluscan shell, teeth, and bone exhibit mutually exclusive mechanical properties due to their hierarchical stratified microarchitectures comprise mineral tablets and interweaved with organic biomaterials. These biological materials have various rough interfaces such as mineral bridges, and nanoasperities on its individual tablet surfaces, which leads to further homogeneous stress distribution within the matrix of the material and augments the mechanical response (flexural strength) of bioinspired materials. Flexural strength being the substantial mechanical property helps in designing structural elements like beams, shafts, cantilevers; in predicting both resistance and durability of the objects; and in the development of constructional materials, which also has necessitated the high flexural strength value in all engineering applications like construction, defence, energy, and aerospace. Hence, biomimicking of these high flexural natural materials (e.g., the flexural strength of the nacreous structure is 220 MPa) can help the engineering community in developing high flexural materials. This chapter discusses the biomimicking of various animal- and plant-based biologically inspired materials for the developing composites materials that have high flexural strength and concludes with the discussion on the future scope of the natural composites.
