| 摘要 |
The purpose of the present invention is to provide a method for obtaining a joint in a short time and at a low current, said joint being very strong, exhibiting little deformation such as warping and being a composite material joint containing thermoplastic resin and carbon fibres. The present invention is a joint manufacturing method which includes each of the following processes: (i) prepare a plurality of composite materials including thermoplastic resin and discontinuous carbon fibres, in which the discontinuous carbon fibres are arranged in a random manner; (ii) overlay the plurality of composite materials; (iii) sandwich at least part of the overlapped portion between a pair of electrodes; and (iv) pass electric current between the electrodes, and solvent weld the thermoplastic resin by means of Joule heat. |
