1.The content of modified fiber affects the mechanical performance of composite, and the mechanical properties of composites with 25% fiber as reinforcement are as follows: 27 MPa of tensionintensity, 40 MPa of bend intensity and 5 kJ/m 2 of strike intensity (indentation).
2.The results show that the tensionintensity of slice is up to 100 MPa and the im- pact intensity up to 25 kJ/m~2,and linear relation between crack section and the fractal dimension is established.
