Method for manufacturing fiber reinforced plastic tubular body, tubular body obtained by the method, and shaft for golf club

摘要

Two or more fiber reinforced plastic intermediate material layers are bonded together, and the fiber reinforced plastic intermediate material is put in a bag-like membrane material, sealed, subjected to a decompression treatment inside, and then taken out of the bag-like membrane material. A method for producing a fiber reinforced plastic (FRP) tubular body, characterized by forming a fiber reinforced plastic intermediate material by winding on the top, and a plurality of lengths of 750 to 1500 mm and a twist strength of 1800 Nm degrees or more An FRP tubular body having a fiber-reinforced plastic intermediate material layer.
