Abstract: Silica rubber pressure molding is one of a new composite molding process. The silica rubber mould and composite preprag are put together into a rigid outer tooling during manufacturing. The silica rubber mould will give pressure on preprag when it is heated. Because the pressure direction of silica rubber is changeable, it can produce many products which can't be produced by some traditional process such as molding or autoclave. This paper introduces the expansion pressure design and pressure detection of silica rubber pressure molding. This paper also introduces the design of casting tooling and transitive silica rubber mold.

Key words: composite, silica rubber, pressure molding
