In consideratioin of technical properties of GF/PVC composite materials prepared with aqueous suspension, a model interfacial design is carried out on fiber/matrix interfacial structures, and serial materials are prepared according to the design. The interface forming mechanism in the preparation and the relation between interfacial structure and material properties are studied. The result shows that the GF/PVC composite materials prepared with aqueous suspension have the advantages of interfacial structure design, the composite materials designed with Model B interface could be used to prepare composite materials with good quality, their quality would be better if the fiber is treated by composite coating.
