Comparative analysis of experimental results and finite element simulation results of ballistic impact on 3D woven reinforced composites

Abstract

In this work, the finite element software (ABAQUS) was used to build a single-cell model based on three-dimensional woven reinforced composite and investigate the propagation of stress waves in the composite. The experimental results of the edge part of the bullet after impact with the results of simulations were compared, and the final damage pattern of three-dimensional woven reinforced composite with commonly used laminates were also comparatively studied. The results indicated that the peak stress of the bullet in the three-dimensional woven reinforced composite increased with increasing incident velocity and was reflected back and forth. The fracture of the reinforcement yarn was rougher after the bullet was ejected from the lower surface of the three-dimensional woven reinforced composite than from the incident upper surface. Delamination did not occur within the three-dimensional woven reinforced composite, and the observed damage holes were generally consistent with the graphs simulated using finite element software. The research in this paper provides a design method for the application of three-dimensional orthogonal hybrid woven reinforced composites in ballistic protection. The experimental results and corresponding calculation methods can guide the design of high-performance protective armor.
