Abstract
Provided are a metal/CFRP composite structure which has lightweight and high strength by combining hot-pressed metal material(s) and carbon fiber reinforced plastic (CFRP) material(s), and its manufacturing method and apparatus. A metal blank material is heated to a temperature at which quenching is possible to obtain a first intermediate product quenched by hot-pressing. The first intermediate product, and a carbon fiber reinforced plastic (CFRP) prepreg comprising carbon fiber and uncured thermoset plastic are set into CFRP forming dies followed by press-forming the prepreg to obtain a secondary intermediate product having the CFRP in intimate contact with a surface of the first intermediate product. The CFRP and the first intermediate product are firmly adhered together by thermal curing of thermoset plastic located in the boundary of the CFRP and the first intermediate product, by subjecting the thermoset plastic contained in the CFRP prepreg to thermal curing.
