Abstract

The aim of this study is to understand the energy absorption mechanism and identified failure modes of the developed multiaxis non-interlaced/non-Z Eglass/ polyester and 3D woven carbon/epoxy composites with soft backing para-aramid fabric structures. The damage zones of both structures were investigated after impact. 3D woven carbon/epoxy showed a small damaged area compared to that of the non-interlaced/non-Z Eglass/ polyester. This was because Z-fiber suppressed the impact load but the local area was severely damaged in the form of fiber and matrix breakages. There was no intra and inter fiber damage around the impacted area in the 3D carbon/epoxy composite whereas there was intra and inter fiber damage around the impacted area in the non-interlaced/non-Z E-glass/polyester.
