As seen from Fig.10(b), composites has a neat fracture, only a handful of fiber is pulled up.The situation indicates that a strong reaction are proceeded between the fiber and the interface of matrix.Crack happened with the fiber ruptured when loads reached a certain value.While the crack propagation has a high degree,the matrix will be cracked and then the materials were overall destructed.
