Abstract

A resin joined body includes a thermoplastic resin molded body and a thermosetting resin molded body. The thermosetting resin molded body has a thermoplastic resin portion embedded in the thermosetting resin molded body and exposed at a portion of a surface of the thermosetting resin molded body. The thermoplastic resin portion of the thermosetting resin molded body is welded to the thermoplastic resin molded body thereby joining the thermosetting resin molded body to the thermoplastic resin molded body.

First claim

What is claimed is:

1. A resin joined body comprising:
a thermoplastic resin molded body; and
a thermosetting resin molded body having a thermoplastic resin portion embedded in the thermosetting resin molded body and exposed at a portion of a surface of the thermosetting resin molded body, the thermoplastic resin portion being welded to the thermoplastic resin molded body thereby joining the thermosetting resin molded body to the thermoplastic resin molded body,
wherein the thermoplastic resin portion includes an anchor portion and a protruding portion,
wherein the anchor portion is embedded in the thermosetting resin molded body, and the anchor portion has a width that is larger than a width of the protruding portion when viewed from a direction orthogonal to the surface of the thermosetting resin molded body, and
wherein the protruding portion is connected to and extends from the anchor portion and protrudes beyond the surface of the thermosetting resin molded body and is welded to the thermoplastic resin molded body.

2. The resin joined body according to claim 1 , wherein
the thermoplastic resin molded body includes fibers therein.

3. The resin joined body according to claim 1 , wherein
the thermoplastic resin portion includes fibers therein.

4. The resin joined body according to claim 1 , wherein
the thermosetting resin molded body has at least two of the thermoplastic resin portions.

5. The resin joined body according to claim 1 , wherein
a composition of a thermoplastic resin material of the thermoplastic resin molded body is identical to a composition of a thermoplastic resin material of the thermoplastic resin portion of the thermosetting resin molded body.

6. A vehicle structure that includes the resin joined body according to claim 1 .

7. A manufacturing method of a resin joined body comprising:
preparing a thermoplastic resin molded body;
preparing a thermosetting resin molded body that includes a thermoplastic resin portion embedded in the thermosetting resin molded body and that is exposed at a portion of a surface of the thermosetting resin molded body; and
joining the thermoplastic resin molded body to the thermosetting resin molded body by welding the thermoplastic resin molded body to the thermoplastic resin portion of the thermosetting resin molded body,
wherein the thermoplastic resin portion includes an anchor portion and a protruding portion,
wherein the anchor portion is embedded in the thermosetting resin molded body, and the anchor portion has a width that is larger than a width of the protruding portion when viewed from a direction orthogonal to the surface of the thermosetting resin molded body, and
wherein the protruding portion extends from the anchor portion and protrudes beyond the surface of the thermosetting resin molded body and is welded to the thermoplastic resin molded body.

8. The manufacturing method according to claim 7 , wherein
the thermoplastic resin molded body includes fibers therein.

9. The manufacturing method according to claim 7 , wherein
the thermoplastic resin portion includes fibers therein.

10. The manufacturing method according to claim 7 , wherein
the thermosetting resin molded body has at least two of the thermoplastic resin portions.

11. The manufacturing method according to claim 7 , wherein
a groove is provided in the surface of the thermosetting resin molded body around a portion where the thermoplastic resin portion is exposed.

12. The manufacturing method according to claim 7 , wherein
a composition of a thermoplastic resin material of the thermoplastic resin molded body is identical to a composition of a thermoplastic resin material of the thermoplastic resin portion of the thermosetting resin molded body.

13. The manufacturing method according to claim 7 , wherein
the thermoplastic resin portion is embedded in the thermosetting resin molded body before a thermosetting material of the thermosetting resin molded body is thermally cured.

14. A resin joined body comprising:
a thermoplastic resin molded body; and
a thermosetting resin molded body that includes a thermoplastic resin portion, the thermoplastic resin portion being provided exposed on a portion of a surface of the thermosetting resin molded body, and the thermoplastic resin portion being welded to the thermoplastic resin molded body,
wherein the thermoplastic resin portion includes an anchor portion and a protruding portion,
wherein the anchor portion is embedded in the thermosetting resin molded body, and the anchor portion has a width that is larger than a width of the protruding portion when viewed from a direction orthogonal to the surface of the thermosetting resin molded body, and
wherein the protruding portion extends from the anchor portion and protrudes beyond the surface of the thermosetting resin molded body and is welded to the thermoplastic resin molded body.
