REINFORCING MEMBER AS FIBER-REINFORCED COMPOSITE ARRANGED IN FASTENING THROUGH-HOLE FORMED IN FASTENED MEMBER AS RESIN MOLDING, AND FASTENING STRUCTURE OF FASTENED MEMBER WITH REINFORCING MEMBER ARRANGED IN THROUGH-HOLE

摘要

PROBLEM TO BE SOLVED: To suppress creep deformation around a through-hole when a reinforcing member as a fiber-reinforced composite is arranged in the fastening through-hole formed in a fastened member as a resin molding.SOLUTION: A core thread 2 and a plaited thread 3 as carbon fibers are formed as a braid-like texture. The reinforcing member 1 as a fiber-reinforced composite includes: a cylindrical cylinder portion 5 fixable to the through-hole 4; and an annular first flange portion 6 and an annular second flange portion 7 which are formed radially outward of the through-hole 4 from the upper and lower ends of the cylinder portion 5. The fastened member 10 as a fiber-reinforced composite and a metal material 12 are fastened to each other by a bolt 8. A head 8a of the bolt abuts on the first flange portion 6. On the inner peripheral surface of the through-hole 4, the cylindrical portion 5 is arranged in a region to be brought into contact with the bolt 8 without any gap. In the cylindrical portion 5, the core thread 2 is directed in the axial 4a direction of the through-hole 4 and oriented at least from one opening of the through-hole 4 to the other opening thereof.
