Modeling and damage repair of woven thermoplastic composites subjected to low velocity impact

The low velocity impact behavior of three layer thermoplastic laminates consisting of woven glass fiber and polypropylene has been investigated for two different fiber volume configurations. Panels with configurations of 50/50 and 20/80 in the warp and fill directions were subjected to low velocity impact energies between 4 and 16 J using an instrumented dropping weight impact tower. Load vs. displacement plots showed the excellent energy...
