摘要

The transverse impact of 3-D multi-layer weft interlaced with warp interlock woven fabric cellular composite was tested under modified split Hopkinson pressure bar and quasi-static loading. The load-displacement curves of transverse impact were obtained to analyze the energy absorption capacity of the composite. The failure load and energy absorption of composite increase as the impact velocity increases. The warp direction and the weft direction of the composite have different energy absorption at each impact velocity. The damage morphology of the composite coupon manifests the compression failure in the front side and tension failure in rear side.
