  • Publication number: 20230332633
    Abstract: An outer member, an inner member, and an inside fixing member overlap each other and fastened together by a fastening member. The outer member is made of fiber reinforced resin, and fibers contained in the fiber reinforced resin-made outer member are arranged in a direction crossing the above-described overlapping direction. A bolt of the fastening member comprises a conical (truncated cone-shaped) middle portion which is poisoned between a head portion and a shaft portion. In a case where the outer member and the bolt are offset from each other in a radial direction of a through hole of the outer member, the conical middle portion partially contacts an edge portion of the through hole and compress a contacted portion of the outer member in the overlapping direction.

    Abstract: Provided is a frame which is made of a fiber reinforced composite and where a bending strength and a vibration damping capability are compatible. The frame which is made of a fiber reinforced composite includes: a compressive wall part where a compressive stress occurs in a longitudinal direction of the frame when the frame receives a bending load in a normal direction perpendicularly intersecting the longitudinal direction; a side wall part extending in the normal direction and defining one of the corners with the compressive wall part; and a tension wall part which is away from the compressive wall part and extends in the longitudinal direction, and where a tensile stress occurs in the longitudinal direction when the frame receives the bending load. The tension wall part has a loss coefficient which is larger than a loss coefficient of the compressive wall part by 0.005 or more.

  • Publication number: 20220274652
    Abstract: A body structure of a vehicle includes a coupling member made of fiber reinforced plastic including fibers impregnated with synthetic resin and a pair of rear fixing members that have a bending rigidity higher than the coupling member and fix both end portions in the longitudinal direction of the coupling member to a vehicle body. Boundary portions between the pair of fixing members and the coupling member are formed in both end portions in the longitudinal direction. A distance between the boundary portions on the rear side is different from that between the boundary portions on the front side that extend along neutral axes defined by the lines of intersection between the neutral plane of bending moments of the coupling member and the lateral cross sections of the coupling member when a bending load is input through the pair of rear fixing members to the coupling member.
