Abstract
For forming a preform of composite material, such as aluminum-based composite material (MMC) by using friction during the forming thereof, ceramic reinforcement, such as Al.sub.2 O.sub.3 and binder are prepared, and the prepared reinforcement and the silanor group binder are put into a die for press forming. During the forming, polycondensation occurs due to frictional heat generated between the fibrous or grain-like particles of the reinforcement and the silanor group binder to harden it, thereby obtaining a preform in which the particles of the reinforcement are fixedly connected to one another.
