Member for frp reinforcement, method for producing same, frp molded body and frp connection structure

An FRP connecting structure, comprising:

• FRP molded bodies being connected to each other or an FRP molded body and a member made of a material different from FRP being connected to each other by a bolt or a rivet,
• wherein an FRP reinforcing member is fixed to the FRP molded body by an adhesive so as to cover a periphery of a bolt hole or a rivet hole of the FRP molded body,
• wherein the FRP reinforcing member comprises a plurality of fiber layers integrated with a resin,
• wherein the plurality of fiber layers include:
• a spiral fiber layer formed by arranging fibers in a spiral shape along a periphery of a hole;
• and
• a cloth-like fiber layer in which fibers are knitted in a lattice pattern,
• wherein at least two layers of the cloth-like fiber layers are laminated so as to sandwich the spiral fiber layer, and
