Method Of Forming Composite Materials

The molding method of composite materials varies according to the matrix material. There are many molding methods for resin matrix composites, including hand lay-up molding, injection molding, filament winding molding, compression molding, pultrusion molding, RTM molding, autoclave molding, diaphragm molding, migration molding, reaction injection molding, soft film expansion. Forming, stamping, etc. The forming methods of metal matrix composites are divided into solid phase forming method and liquid phase forming method. The former is formed by applying pressure at a temperature lower than the melting point of the matrix, including diffusion welding, powder metallurgy, hot rolling, hot drawing, hot isostatic pressing and explosive welding. The latter is to melt the matrix and fill it into the reinforcement material, including traditional casting, vacuum suction casting, vacuum reverse pressure casting, squeeze casting and injection casting, etc. The forming methods of ceramic matrix composites mainly include solid phase sintering, chemical Vapor infiltration molding, chemical vapor deposition molding, etc.
