Abstract
A joining method using heat fusion includes layering a first joining body and a second joining body having a smaller plane area than the first joining body; and performing heating and pressurization with a heater from a side of the second joining body. The method further includes a resin dam interposed between the second joining body and the heater. The resin dam includes a base body having one of front and back surfaces in contact with the heater and the other of front and back surfaces in contact with the second joining body; and a dam main body extending from a circumferential edge of the base body in a direction away from the base body and having a shape control surface facing a side surface of the second joining body.
Claims5
A joining method using heat fusion, the joining method comprising:
- a first step of layering a first joining body and a second joining body having a smaller plane area than the first joining body;
- and
- a second step of performing heating and pressurization with a heater from a side of the second joining body, wherein
- in the second step, a resin dam is interposed between the second joining body and the heater, and
- the resin dam includes
- a base body having one of front and back surfaces in contact with the heater and the other of front and back surfaces in contact with the second joining body and
- a dam main body extending from a circumferential edge of the base body in a direction away from the base body and having a shape control surface facing a side surface of the second joining body,
- wherein each of the first joining body and the second joining body is made of a thermoplastic composite material,
- the second joining body is heated and melted so as to be heat-fused to the first joining body, and
- the resin dam controls a shape of a resin that is extruded from the second joining body.
