Abstract

Numerical study was carried out for layered composite plates joined with both interspaced and interspaced double-lap joint subject to tensile load. The numerical analyses were actualized using ANSYS 14.5 software package based on finite elements method. The layered composite plates with different orientation angles were considered. It was considered that the composite plates and patches were carbon/epoxy (AS4/3501-6) and the composite plates were joined using DP 410 adhesive. The studies started with the determination of the failure loads the stresses in these loads were obtained. Normal and shear stress in all directions were obtained via numerical analyses for composite layers and adhesive layers throughout radial thickness. Moreover, the von–Mises stress distributions that develop on the adhesive were obtained as well. The effects of adhesive and orientation angles were examined at the adhesive and composite layers interfaces. The effect of the surfaces is great in the gap-free bonding of the surfaces. But the strength of the adhesive is more important than the condition of the adhesion surfaces in interspaced bonding.

Keywords: adhesive; finite element method; joint design; orientation angles; stress analysis
