  • Publication number: 20230182415
    Abstract: A method for manufacturing a fiber-reinforced resin tube body includes: a preparing step of preparing a cylindrical expandable body having fiber wound therearound; an installing step of installing the expandable body in a mold after the preparing step; a flowing step of flowing resin into the mold, in which the expandable body is placed, after the installing step; and an expanding step of expanding the expandable body toward an inner wall of the mold after the flowing step.

  • Publication number: 20220063218
    Abstract: A continuous forming apparatus of a fiber reinforced composite includes a tension detection mechanism, a drive motor, and a drive control device. The drive control device is configured so that a material roll is rotationally driven in a delivery direction of a reinforced fiber base material during a time period from a time point of end of pressurization in a forming process to a time point of end of a pulling-out process, and is also configured to perform tension control on the reinforced fiber base material based on a detected tension value from the tension detection mechanism and a target tension value, during a time period from a time point of start of the pulling-out process to a time point of end of the pressurization in the forming process in a next forming operation.

  • Publication number: 20210252767
    Abstract: A roll-forming apparatus includes a heating portion, and a shaping portion disposed downstream of the heating portion in a conveyance direction of a fiber reinforced plastic member to shape the fiber reinforced plastic member heated by the heating portion. The shaping portion includes a first forming roller pair, and a second forming roller pair disposed downstream of the first forming roller pair in the conveyance direction. A rotational speed of the second forming roller pair is set higher than a rotational speed of the first forming roller pair to apply a tension in the conveyance direction to the fiber reinforced plastic member between the first forming roller pair and the second forming roller pair.
