MEMBER FOR FRP REINFORCEMENT, METHOD FOR PRODUCING SAME, FRP MOLDED BODY AND FRP CONNECTION STRUCTURE

摘要

[Problem] The present invention provides: a member for FRP reinforcement to be used for the purpose of suppressing the occurrence and growth of a crack in a bolted part, a rivet joined part or a bent part having an extremely small bending radius under the circumstances where there has been an increasing demand for the reduction in weight and thickness of an FRP molded body; and a method for producing this member for FRP reinforcement. [Solution] A member for FRP reinforcement according to the present invention is used by being bonded to an FRP molded body, and is obtained by integrating a plurality of stacked fiber layers by means of a resin. This member for FRP reinforcement is characterized in that: the plurality of fiber layers include a spiral fiber layer which is formed by spirally winding fibers and two or more cloth-like fiber layers which are formed by knitting fibers in a lattice pattern; the plurality of fiber layers additionally include a spiral fiber layer which is formed by spirally winding fibers and a cloth-like fiber layer which is formed by knitting fibers in a lattice pattern, while having a configuration wherein at least two cloth-like fiber layers are stacked, with a spiral fiber layer being sandwiched therebetween; and the fibers are composed of glass fibers, carbon fibers and aramid fibers.
