PURPOSE:To provide a stamping molding material wherein sagging properties (drawdown resistance) at the time of shifting to a mold from a heating furnace can be improved, the surface is free from stickiness, handling can be performed easily and the thing itself can be manufactured easily. CONSTITUTION:A stamping molding material 10 is formed by laminating a base 20 made of thermoplastic resin 21 such as polypropylene reinforced by a short fiber 22 such as a glass fiber and a skin material 30 having a higher softening temperature than that of the base 20 each other. Especially, in the case where the base 20 is taken as glass-fiber-reinforced polypropylene, drawdown resistance can be improved by allowing the base 20 to contain the 5-50wt.% glass fiber having a fiber length of 0.1-5mm and 95-50wt.% polypropylene whose intrinsic viscosity (eta) is 0.5-2.5. |
