STAMPING-MOLDING MATERIAL AND STAMPED-MOLDING

摘要

PURPOSE:To provide the subject material capable of being readily ribbed and molded into complicated shape while having the strength, the elastic modulus, etc., in a direction, by laminating a layer comprising an oriented short fiber- reinforced material to a layer comprising a non-oriented short fiber-reinforced material. CONSTITUTION:The objective material comprises a laminated or joined product of a layer (a) composed of an oriented short fiber-like reinforcing material and a thermoplastic resin to a layer (b) composed of a non-oriented short fiber- like reinforcing material and a thermoplastic resin. The thermoplastic resin is preferably a crystalline resin such as polypropylene. The short fiber-like reinforcing material is preferably carbon fibers or glass fibers. The material is preferably produced by a method comprising molding a solution containing the resin and the short fiber-reinforcing material in a head box 3 having regularly oriented projections to form a fiber-reinforced web 5 and subsequently molding a solution containing the resin and the short fiber-like reinforcing material in a head box 13 not having projections to form a fiber-non-oriented web on the web 5.
