Abstract

The invention provides 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 comprise 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 reingorcing 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 comprises 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.

Description

technical field

[0001] The present invention relates to a fiber-reinforced plastic, which is a plate-shaped body having a plate-shaped portion and a raised portion protruding from at least one side of the plate-shaped portion, and a method for producing the same. It is formed of a plurality of reinforcing fibers and a matrix resin integrated with the plurality of reinforcing fibers.

[0002] As a typical example of the above-mentioned plate-shaped body having a protrusion, there is a plate-shaped body having a rib or a boss. The plate-shaped body is widely used as a structural member. Examples of such structural members include those used in transportation machines such as automobiles, sports equipment such as bicycles, and the like. Background technique

[0003] Fiber-reinforced plastics composed of reinforcing fibers and matrix resins have high specific strength and specific elastic modulus, excellent mechanical properties, and high-performance properties such as weather...
