Metal fiber composite plate and preparation method thereof

Relating to the composite material field, the invention discloses a metal fiber composite plate and a preparation method thereof. The preparation method of the metal fiber composite plate includes: putting a first metal plate into a laminating mold, then laying a first thermoplastic resin powder layer, a fiber cloth, a second thermoplastic resin powder layer and a second metal plate successively on the surface of the first metal plate, then performing hot press molding at a temperature of thermoplastic resin powder melting temperature+/-20DEG C, wherein the first metal plate surface at least attached with the first thermoplastic resin powder layer and the second metal plate surface at least attached with the second thermoplastic resin powder layer respectively have an average pore size of0.1-50microm independently. The preparation method of the metal fiber composite plate provided by the invention can simplify the procedure and improve production efficiency, also the obtained metal fiber composite plate has h
