Document Type and Number:
Japanese Patent JP7236725
Kind Code:
B2
Abstract:
Provided is a fiber-reinforced resin bolt having a strength higher than that of a conventional fiber-reinforced resin bolt. A fiber-reinforced resin bolt 1 formed by a winding step of winding a CFRP resin tape 14, which is formed in a band shape by integrating CFRP 12 with a thermosetting resin in such a manner that the CFRP 12 is oriented in a longitudinal direction, so that the CFRP 12 is arranged concentrically around a winding axis, thereby forming a CFRP resin tape layer 10; and a curing step of placing the CFRP resin tape layer 10 formed by the winding step in a die 40 whose inner wall surface is formed with a screw shape, pressurizing the die 40 in which the CFRP resin tape layer 10 is placed from one direction of the winding axis to the other, and heating the die 40 with a heater 82, thereby curing the resin containing the CFRP resin tape layer 10.
