  • Composite material structure and method for manufacturing composite material structure
    Patent number: 11763958
    Abstract: Provided are a composite material structure obtained by joining composite materials with resin-impregnated reinforcing fibers, for which appropriate lightning proofing measures are taken, and a method for manufacturing the composite material structure. The composite material structure includes a first composite material, a second composite material, and a low-conductivity material. The first composite material includes a conductive first reinforcing fiber and a first resin impregnated into the first reinforcing fiber. The second composite material is integrated with the first composite material, and has a conductive second reinforcing fiber and a second resin impregnated into the second reinforcing fiber.
    Type: Grant
    Filed: January 23, 2019

  • COMPOSITE MATERIAL STRUCTURE
    Publication number: 20230078838
    Abstract: This composite material structure is provided with: a first composite material that is obtained by stacking a plurality of first composite material sheets, each of which is obtained by impregnating electroconductive first reinforcing fibers with a first resin; a second composite material which is obtained by impregnating electroconductive second reinforcing fibers with a second resin; an insulating bonding layer that is arranged between the first composite material and the second composite material, thereby bonding the first composite material and the second composite material to each other; and an electroconductive member that connects the plurality of first composite material sheets.
