Tensile Failure of Unidirectional Composite Laminates

摘要：

　　The 0° tensile failure behaviors of unidirectional composite laminates of carbon fiber reinforced polymer matrix and glass fiber reinforced polymer matrix were studied by tensile testing at -55℃,room temperature and 70℃,respectively,as well as observation of the fracture characteristics.The failure modes and influencing factors were analyzed.The results show that there exist two types of failure modes of the unidirectional composite laminates at 0°tensile test: the fracture of fiber and matrix,and the interface failure.Because of different ratio of the two failure modes,there exist different fracture characteristics.Failure modes and fracture characteristics mainly depend on the interface strength of the fiber and matrix.The effect of test temperature,fiber and matrix on the fracture characteristics and failure modes is mainly related to the interface strength.
