study of hybrid composite joints with thin-ply-reinforced adherends under high-rate and impact loadings

This research aims to examine the tensile strength of a hybrid composite laminate reinforced by thin-plies when used as an adherend in bonded single lap joints subjected to high-rate and impact loading. two different composites, namely texipreg hs 160 t700 and ntpt-tp415, are employed as the conventional and thin-ply composites, respectively. the study considers three configurations: a conventional composite, a thin-ply, and a hybrid single lap joint. numerical models of the configurations are developed to provide insight into failure mechanisms and the initiation of damage. the results indicate a significant increase in tensile strength for the hybrid joints over the conventional and thin-ply joints, due to the mitigation of stress concentrations. overall, this study demonstrates the potential of hybrid laminates for improving the performance of composite joints under high-rate loading and impact conditions.
