PURPOSE:To manufacture a glass fiber reinforced sheet of which an extremely superior appearance product can be molded having an improved falling weight impact strength and rigidity. CONSTITUTION:(A) is used as a core layer, and (B) is used as a thin as a skin layer covering one side or both sides of the core layer, and the thickness of the skin layer is formed at least 0.5mm on one side, and 20-100% of the thickness of the core layer in the multi-layer extrusion molding, in the above (A) is a pellet composed of glass fiber roving impregnated with thermoplastic resin and cut into the length of 5 to 30mm, and (B) is thermoplastic resin not containing a fibrous reinforcing material. |
