PURPOSE: To produce a lightweight molding substrate, excellent in heat resistance by blowing off glass continuous filaments and thermoplastic resin continuous filaments onto the same conveyor, depositing the filaments thereon, forming a mat and laminating nonwoven fabrics onto both surfaces of the resultant mat.
CONSTITUTION: Glass fibers A and A' and thermoplastic resin fibers B and B' are blown off from separate feeders 11a, 11a', 11b and 11b' onto the same conveyor 10 and deposited thereon. A mat is then formed on a nonwoven fabric 12 by a method, etc., for placing the nonwoven fabric 12 which is a substrate outer material on the conveyor 10 and another nonwoven fabric is arranged from the upper part of the mat. The mat is sandwiched therebetween, thermally compressed and integrated to afford the substrate for molding.
