MOLD FOR FIBER-REINFORCED RESIN JOINT AND METHOD OF MANUFACTURING FIBER-REINFORCED RESIN JOINT USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To mold a plurality of fiber-reinforced resin joints through a single molding operation. PSOLUTION: The mold body 22 of a mold 2 is contracted, and, after a plurality of sealing rubber rings 110 are attached at predetermined positions on the outer peripheral surface of the mold body 22 at spacings in the longitudinal direction, the mold body 22 is expanded. The rotation shaft 21 of the mold 2 is supported in a freely rotatable way, and at least cutting grooves 22a of the mold body 22 is covered with a release film f by laminating the release film f on the outer peripheral surface of the mold body 22. The mold 2 is rotated to wind and laminate a reinforcing fiber bundle impregnated with a polymerizable resin composition around the outer peripheral surface of the mold 2, and the polymerizable resin composition impregnated in the wound reinforcing fiber bundle is hardened to form a fiber-reinforced resin layer 120. The fiber-reinforced resin layer 120 is cut at positions corresponding to each of cutting grooves 22a with a cutter to divide it into the plurality of pieces. The mold body 22 is then contracted, and each of divided pieces of the fiber-reinforced resin layer 120 are released sequentially. PCOPYRIGHT: (C)2011,JPO&INPIT
