PURPOSE: To obtain a molding strengthened in a three-dimensional direction by employing a mat needle punched after a glass fiber strand imparted a bundling agent for strengthening a bunding force of a resin and a glass fiber is accumulated by a free falling.
CONSTITUTION: A bundling agent with a performance of strengthen a bonding force with a resin is applied to a glass fiber filament spun out and a strand S thus obtained by bundling is accumulated on a belt 27 of a conveyor 24 covering the entire width with a strand distributor 20 to form a mat 28. Then, a part of the strand is pushed thicknesswise into the mat by needle punching and impregnated with a thermosetting resin to mold by hardening.
