  • Patent number: 12089388
    Abstract: A composite material structure includes: a first composite material member including a first reinforcing fiber that is electrically conductive and impregnated with a first resin; a second composite material member including a second reinforcing fiber that is electrically conductive and impregnated with a second resin; an adhesive layer disposed between the first composite material member and the second composite material member to bond the first composite material member to the second composite material member; and an electromagnetic shielding member covering at least part of an area, exposed to an exterior, of the adhesive layer. At least one of the first and second composite material members has a predefined lightning current direction in which a lightning current generated by a lightning strike passes. The shielding member is disposed over an entire plane of a side face in a direction orthogonal to the lightning current direction.
