Title:
FIBER-REINFORCED RESIN COMPOSITE AND MANUFACTURING DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/026329
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a fiber-reinforced resin composite in which fiber-reinforced resins are joined together, which has sufficient durability, and which is capable of being manufactured at low cost; and a manufacturing device therefor. A fiber-reinforced resin composite (20) comprises a plurality of fiber-reinforced resins (10, 11) joined together, the fiber-reinforced resins (10, 11) having a resin containing a dynamic covalent bond as a matrix resin and reinforced fibers arranged inside the resin. The fiber-reinforced resins (10, 11) are sutured together using a suture thread (21), whereby the fiber-reinforced resin composites (11, 11) are joined together. The fiber-reinforced resin composite (20) is manufactured by means of a manufacturing device provided with: a suture device provided with a suture needle (22) for suturing the fiber-reinforced resins (10, 11) together using a suture thread (21); and a heating device that heats and softens a resin existing in front of and under the suture needle and/or in front of and to the rear of the suture needle in a direction of sewing by the suture device.
