  • Patent number: 10357926
    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.

  • Publication number: 20180272630
    Abstract: A metal plate, a fabric formed of reinforcing fibers, and thermosetting adhesives are layered on each other in a die in a die clamping direction. The thermosetting adhesives are forced to enter the fabric by clamping the die to produce a fiber reinforced plastic material with the thermosetting adhesives therein being in an uncured state. At the same time, the fiber reinforced plastic material is molded into a shape specified by the die. The thermosetting adhesives are allowed to cure in the die to cure the molded fiber reinforced plastic material, and the fiber reinforced plastic material and the metal plate are bonded each other.

  • Patent number: 8839652
    Abstract: In a method for press-hardening a metallic formed structure made of a hardenable steel sheet, the steel sheet is heated above a transition temperature Ac3 and then placed in a cooled press having a forming tool with at least one uncooled contour section for forming a region of reduced hardness. Marginal regions of the steel sheet are clamped with a sheet holder arrangement which has an inner sheet holder and an outer sheet holder. The inner sheet holder is hereby located closer to the forming tool than the outer sheet holder. The sheet holder arrangement is configured to slow down flow of the marginal regions into the forming tool. After closing the press tool, the steel sheet is formed in a first forming phase by holding the marginal region with the outer sheet holder and in a subsequent forming phase by holding the marginal region with the inner sheet holder.
