Abstract
A molded carbon-fiber-reinforced plastic (molded CFRP) includes a plurality of carbon fiber layers having carbon fibers, a resin body in which the carbon fiber layers are buried, and pins which are inserted and fixed in a plurality of holes formed in the resin body so as to extend through the carbon fiber layers. In the molded CFRP, the pins can be inserted and fixed in the plurality of holes formed in the resin body so as to extend through the carbon fiber layers, to thereby improve interlaminar toughness of the molded CFRP.
Claims7
A molded carbon-fiber-reinforced plastic comprising:
- a plurality of carbon fiber layers comprising carbon fibers;
- a resin body in which the carbon fiber layers are buried;
- and
- pins which are inserted and fixed in a plurality of holes formed in the resin body so as to extend through the carbon fiber layers.
A process for producing a molded carbon-fiber-reinforced plastic, comprising:
- a step of laminating a plurality of prepregs containing carbon fibers to obtain a prepreg laminate;
- a step of forming a plurality of holes in the prepreg laminate so as to extend through the prepregs;
- a step of inserting pins in the holes;
- and
- a step of curing the prepreg laminate by heat with the pins inserted in the holes to obtain a molded carbon-fiber-reinforced plastic.
