The formation mechanism of the interface and interface layer Relationship between structure and material properties. The results show that the preparation of GF / PVC composites by aqueous suspension method is conducive to the design of interfacial layer structure. The composites designed by interfacial layer model B can be used to prepare composite materials with good properties. If the fibers are treated by composite coating, the effect is more it is good
