A method of controlling fiber movement during formation of a laminate of fibers in a thermoplastic resin matrix into a desired shaped comprising the steps of: providing a laminate of fibers in a thermoplastic resin matrix to be formed into a desired shape; rough forming said laminate into an approximation of said desired shape in a first shaping die having a surface portion, said first shaping die having piercing studs protruding from said surface in a preselected pattern for piercingly engaging said laminate in operation, and making holes therein; completing the formation of said laminate in a second shaping die in the form of said desired shape, said second shaping die being free of said protruding piercing studs, whereby said holes formed by said piercing studs in said laminate are healed during said forming of said desired shapes.
