A Study on the Impact Fracture Behavior of Glass Fiber Polypropylene Composites

GF/PP 복합재료의 충격파괴거동에 관한 연구

  • Published : 1999.11.01


The critical fracture energy and failure mechanisms of GF/PP composites are investigated in the temperatures range of the ambient temperature to $-50^{\circ}C$ The critical fracture energy increase as fiber volume fraction ratio increased The critical fracture energy shows a maximum at ambient temperature and it tends to decrease as temperature goes up. Major failure mechanisms can be classfied such as fiber matrix debonding, fiber pull-out and/or delamination and matrix deformation.
