Title:
COMPOSITE MATERIAL STRUCTURE, AND METHOD FOR MANUFACTURING COMPOSITE MATERIAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/181184
Kind Code:
A1
Abstract:
Provided are: a composite material structure obtained by joining of composite materials in which reinforcing fibers are impregnated with a resin, wherein appropriate lightning-proofing measures are taken; and a method for manufacturing the composite material structure. A composite material structure 10 includes a first composite material 11, a second composite material 12, and a low-electroconductivity material 13. The first composite material 11 has electroconductive first reinforcing fibers and a first resin impregnated into the first reinforcing fibers. The second composite material 12 is integrated with the first composite material 11, and has electroconductive second reinforcing fibers and a second resin impregnated into the second reinforcing fibers. The low-electroconductivity material 13 has electrical resistance that is lower than that of the first resin and the second resin, has low electroconductivity equal to or greater than that of the first reinforcing fibers and the second reinforcing fibers, and electrically connects the first reinforcing fibers and the second reinforcing fibers.
