The Performance of 2.5D Woven Polymeric Matrix Composites under Ballistic Impact Loadings

摘要

By using a gas gun apparatus, three types of 2.5D woven composites and one type of laminated composite under ballistic impact loadings were tested under ballistic impact loadings. The trajectory of the projectile was recorded by high speed camera and then analyzed to obtain the impact and residual velocities. The analysis of the experimental data suggests that the GF-2 composite has the highest impact resistance, followed by GF-1, CF-IM7 and QI-IM7. However, if the difference in density is considered, the three types of 2.5D woven composites have similar efficiency in resisting penetration. The failure and damage modes of the tested plate were visually observed.
