RESISTANCE PERFORMANCE OF KEVLAR/UHMWPE FIBER HYBRID COMPOSITES

Abstract

Abstract: The bulletproof property of Kevlar/UHMWPE fiber interlayer hybrid composites was studied. The composites with different strike face and hybrid ratio were theoretically analyzed by LS-DYNA. Also, process of bullet penetrating composites material is simulated, from which the stress and deformation process diagrams of composite materials are obtained. Moreover, the effect of hybrid ratio and strike face was studied by experiments, the fracture of the fibers was studied and the failure mechanism of the composites was further obtained. The results show that when aramid fibers work as strike face, resistance performance of hybrid composites is better. Furthermore, when the hybrid ratio is 1∶2, the resistance performance is the best.

Key words: interlaminated hybrid composites, ANSYS/LS-DYNA finite element analysis, penetration
