Abstract
A fiber-reinforced plate-like plastic having a plate and a protrusion rising on the plate, wherein the plate and the protrusion each contain a laminated structure composed of plural reinforcing fiber sheets which each include many fibers of 10 to 100 mm in fiber length arranged in a fixed direction and at least two of the layers constituting the laminated structure are different in the direction of arrangement of reinforcing fibers and wherein at least part of the reinforcing fibers extend continuously from the plate to the protrusion and at least one of the layers constituting the laminated structure of the protrusion has a shape similar to the shape of the protrusion; and a process for the production of fiber-reinforced plastic which includes cutting a unidirectional prepreg sheet composed of many reinforcing fibers arranged in a fixed direction and a matrix resin into prepreg base material sheets with the above fiber length, laminating the prepreg base material sheets with the directions of arrangement of reinforcing fibers of the base material sheets being different from each other to form a prepreg laminate, and heating and pressure-molding this laminate in a mold provided with a recess for forming the production.
