Abstract

A joining method for joining a first member having a hole that is opened on at least one surface, to a second member including a material of which a melting temperature is lower than that of a constituent material of the first member, includes: laminating the second member on the first member so as to cover an opening of the hole; and introducing that material of the second member which is softened or melted into the hole through the opening and curing the material of the second member.

First claim

The invention claimed is:

1. A joining method for joining a first member having a hole that is opened on at least one surface, to a second member made of a fiber reinforced resin member configured such that a fiber material is mixed in resin of which melting temperature is lower than that of a constituent material of the first member, the joining method comprising:
laminating the second member on the first member so as to cover a first opening of the hole;
orienting the fiber material contained in the second member in a laminating direction while softening or melting of the resin of the second member above the first opening of the hole;
introducing the fiber reinforced resin member resin mixed with the resin softened or melted into the hole through the first opening by pushing the fiber reinforced resin member resin; and
curing the resin introduced into the hole.

2. The joining method according to claim 1 , wherein:
the second member includes the fiber material whose length is longer than a diameter of the first opening of the hole.

3. The joining method according to claim 1 , wherein:
the hole of the first member has a reduced diameter portion reduced in diameter continuously or in a stepped manner toward the first opening.

4. The joining method according to claim 3 , wherein:
a sectional area of the hole of the first member along a direction perpendicular to the laminating direction is minimized at the first opening.

5. The joining method according to claim 1 , wherein:
the hole of the first member is formed so as to penetrate from the one surface to the other surface opposite to the one surface.

6. The joining method according to claim 5 , wherein:
a backing member configured to cover a second opening of the hole which is formed on the other surface is disposed.

7. The joining method according to claim 6 , wherein:
the backing member includes a depression communicating with the hole via the second opening of the hole which is formed on the other surface and configured such that a sectional area of the depression along the direction perpendicular to the laminating direction is larger than that of the second opening on the other surface; and
in the introducing and curing of the resin of the second member, the resin of the second member is introduced into the depression as well as the hole, and then cured.

8. The joining method according to claim 1 , wherein:
in the introducing and curing of the resin of the second member, the resin of the second member is softened or melted by use of frictional heat.
