Finite element analysis of hybrid 3D orthogonal woven composite subjected to ballistic impact with multi-scale modeling

The present study deals with the finite element analysis (FEA) of hybrid 3D orthogonal woven composite (3DOWC) subjected to ballistic impact by a conical-cylindrical projectile. The present simulation incorporates the micro-meso-macro transition approach is used for developing the intricate design of the target plate. The glass fibers are used for Warp and Weft direction, and Kevlar fibers are considered for the z-direction binder yarns. The model is approved by utilizing 2D weave design, which has been examined by impacting the conical-cylindrical projectile and compared with the available literature. Furthermore, the ballistic analysis is extended for the Hybrid 3DOWC, where the effect of residual velocity and energy absorptions are studied. The study highlights that z-direction fibers have not much influence on energy absorption for both the hybrid and unhybridized 3DOWC. Furthermore, the influence of hybridization will subside with the increased velocities.

Automated summary

This study focuses on the finite element analysis of hybrid 3D orthogonal woven composite subjected to ballistic impact, using a micro-meso-macro transition approach. The results show that z-direction fibers have limited influence on energy absorption, and the effect of hybridization diminishes as velocity increases.
