Problems solved by technology

[0004] However, in a fiber-reinforced thermoplastic resin part, when the heating temperature is increased to sufficiently heat the part to be joined, the temperature of the surface away from the joint surface is also increased due to heat transfer by the reinforcing fibers.
Here, in the method of performing natural cooling after heating the part to be joined, the temperature of a part of the surface of the part to be joined may exceed the melting temperature to cause surface swelling, etc., which may cause appearance defects.
[0005] That is, in the case of heating and joining a plurality of fiber-reinforced thermoplastic resin parts by the heating unit, compared with the method of only using natural cooling for cooling after heating, the joint part of the joining target part is guaranteed to be more efficient. There is room for improvement in the aspect of suppressing the appearance defect of the joint target part while reducing the shear strength

Abstract

A fiber-reinforced thermoplastic resin member welding method includes: heating, by a heating unit, a welding target portion in which plural fiber-reinforced thermoplastic resin members layered on topof each other, each of the plural fiber-reinforced thermoplastic resin members including thermoplastic resin as a main composition, and the thermoplastic resin including reinforcing fibers; applying pressure, by a pressure applying unit, to the welding target portion; and cooling, by a cooling unit, at least a surface of the welding target portion at the same time as when the welding target portion is being heated by the heating unit or after the welding target portion has been heated by the heating unit.

Description

technical field [0001] The present disclosure relates to a joining method and joining device of fiber-reinforced thermoplastic resin components. Background technique [0002] In Japanese Unexamined Patent Application Publication No. 2004-160675, a welding method is disclosed in which, when a part made of thermoplastic resin is welded on a product body made of thermoplastic resin, the Welding is carried out with the thermoplastic resin film of the area between the welding parts interposed. [0003] In the case of heating and joining a portion to be joined in which a part of a plurality of fiber-reinforced thermoplastic resin members are laminated by a heating unit, it is necessary to sufficiently heat the portion to be joined in order to ensure the shear strength of the joined portion to be joined. to melt it. [0004] However, in a fiber-reinforced thermoplastic resin component, when the heating temperature is increased in order to sufficiently heat the part to be joined, ...
