The forming methods of composite materials vary depending on the substrate material. There are many molding methods for resin based composite materials, including hand layup molding, spray molding, fiber winding molding, molding, pultrusion molding, RTM molding, hot pressing can molding, diaphragm molding, migration molding, reaction injection molding, soft film expansion molding, stamping molding, etc. The forming methods of metal matrix composite can be divided into solid forming method and liquid forming method.
The former is formed by applying pressure at a temperature lower than the melting point of the substrate, 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 materials, including traditional casting, vacuum suction casting, vacuum back pressure casting, squeeze casting and spray casting, etc. The forming methods of ceramic matrix composite mainly include solid sintering, chemical vapor infiltration molding, chemical vapor deposition molding, etc.
