PURPOSE:To obtain the composite material characterized by arranging mutually interlaced inorganic fibers in the surface and thickness directions, integrally binding the inorganic fibers in the state having many pores in the fibers, arranging the free ends of fibers on both the front and back surfaces in specific directions to form a reinforcing layer, and having a strength distribution corresponding to uses. CONSTITUTION:The inorganic fibers such as glass fibers or rock wool are mutually interlaced, arranged in the surface direction and in the thickness direction, and integrally bound to each other with a thermoplastic resin in the state having many pores in the fibers to form the square fiber composite material in which the ends of the fibers are free. Subsequently, the free ends of the fibers are arranged in the length or width direction on the side of the front surface or in the other direction on the side of the back surface, arranged in the length direction or width direction on both the front and back sides surfaces, or arranged in the length direction in the parts to be strengthened in the length direction or in the width direction in the parts to be strengthened in the width direction on both the front and back side surfaces, and subsequently integrally bound to each other with a thermoplastic resin. |
