Dynamic impact behavior of 3-D woven fabric composite

For understanding the dynamic mechanical properties of textile structural composites and better designing and application of them,both the static and dynamic mechanical properties of 3-D multi-layer weft interlaced with warp interlock woven fabric composite were tested with a modified split Hopkinson pressure bar(SHPB) apparatus.It was found that this fabric composite is stress sensitive.The bearing ability and energy absorption of the composite increase with the increase of compact velocity.The damage morphology of the composite manifests the compression failure on the face and tension failure on the back.
