Abstract

A joint ( 20 ) joins a plate member ( 26 ) with a preform ( 22 ), wherein an inclined part ( 28 ), which is inclined relative to a surface that is orthogonal to the direction in which a tensile load is applied to the plate member ( 26 ), is formed on a surface ( 25 ) that joins with the preform ( 22 ). Moreover, an indented part ( 38 ) corresponding to the shape of the inclined part ( 28 ) is formed on the preform ( 22 ) so that the inclined part ( 28 ) of the joint ( 20 ) is embedded into the indented part ( 38 ). The joint ( 20 ) is embedded in and bonded to the preform ( 22 ).

First claim

The invention claimed is:

1. A joint for connecting a member to a preform, the joint comprising:
an inclined part inclined relative to a surface orthogonal to a direction in which a tensile load is to be applied to the member,
wherein the inclined part is configured to be embedded in the preform and to be bonded to the preform, and is formed with a plurality of inclined surfaces.

2. The joint according to claim 1 , wherein a surface opposite the inclined part is inclined toward an edge of the joint so that a thickness of the joint at the edge is thinner than a thickness of the joint at a center.

3. The joint according to claim 1 , wherein the plurality of inclined surfaces are formed with different angles with respect to the preform.

4. An aircraft structure, comprising:
a member;
a preform; and
a joint that is provided between the member and the preform, and that connects the member to the preform,
wherein the joint includes an inclined part inclined relative to a surface orthogonal to a direction in which a tensile load is applied to the member,
wherein the preform includes an indented part corresponding to a shape of the inclined part of the joint,
wherein the inclined part of the joint is embedded in the indented part of the preform, and
wherein the inclined part of the joint is bonded to the preform, and is formed with a plurality of inclined surfaces.

5. An assembly comprising:
a member;
a preform; and
a joint that is provided between the member and the preform, and that connects the member to the preform,
wherein the joint includes an inclined part inclined relative to a surface orthogonal to a direction in which a tensile load is applied to the member, and
wherein the inclined part is embedded in the preform and bonded to the preform, and is formed with a plurality of inclined surfaces.

6. The assembly according to claim 5 , wherein a surface opposite the inclined part is inclined toward an edge of the joint so that a thickness of the joint at the edge is thinner than a thickness of the joint at a center.

7. The assembly according to claim 5 , wherein the plurality of inclined surfaces are formed with different angles with respect to the preform.
