| titleOfInvention | Prepreg laminate, composite structure, and method for manufacturing composite structure |
| abstract | The purpose of the present invention is to obtain a prepreg laminate that is a fiber-reinforced plastic material having high rigidity and low weight and moreover having exceptional properties for molding into complicated shapes.　The present invention is a prepreg laminate obtained by a prepreg (A), in which non-continuous reinforcing fibers are impregnated with a thermosetting resin or a thermoplastic resin, and a prepreg (B), in which non-continuous reinforcing fibers are impregnated with a thermoplastic resin, being adjacently laminated, and by the prepreg (A) being disposed on at least one surface, at least some combinations of the adjacent prepregs (A) and (B) forming an overlap region that satisfies (1) and/or (2) below. (1) The coefficient of variation in the fiber length of the non-continuous reinforcing fibers included in the prepreg (B) is greater than the coefficient of variation in the fiber length of the non-continuous reinforcing fibers included in the prepreg (A). (2) The prepreg (B) has a plurality of notches at which the non-continuous reinforcing fibers included in the prepreg (B) are cut, and the average value of a two-dimensional orientation angle of the non-continuous reinforcing fibers included in the prepreg (B) is greater than the average value of a two-dimensional orientation angle of the non-continuous reinforcing fibers included in the prepreg (A). |
