Abstract

PURPOSE:To obtain a product in complicated shape, by a method wherein an uncured fiber reinforced plastic material having a continuous cross section made of long or/and short fiber is arranged within a blocked mold, a punch is pressed against the cross section of the material in a right angle direction, a temperature of the mold is controlled and kept within the mold. CONSTITUTION:A material 1 made of uncured fiber reinforced plastics having a continuous cross section manufactured by combining flat-platelike long fiber or short fiber and both of them is arranged between a top and bottom forces 2, 3 both the forces are made into a blocked state by applying force to them, a top and bottom punches 5, 6 are moved at a predetermined rate, the material 1 is pressed and deformed in the direction meeting at right angles with its cross section, and a molded article in a required shape is obtained by making the inside of a gap 4 fill with the fiber reinforced plastics. On the one hand, curing of the plastics is completed by controlling the foregoing forces 2, 3 at a predetermined temperature and maintaining for a predetermined period of time. Thus a product in high quality and complicated shape is obtained.
