Title:
接合構造
Document Type and Number:
Japanese Patent JP7248518
Kind Code:
B2
Abstract:
To inhibit increase of the weight of a joint structure and reduce a difference of thermal deformation amounts between members.SOLUTION: In a joint structure 10, a first member 12, formed by a fiber-reinforced composite material, and a second member 14, formed by a material having a larger linear expansion coefficient in an in-plane direction than that of the first member 12, are joined. A joint portion between the first member 12 and the second member 14 is provided with an adjustment part 22 which is formed having a substantially hat-shaped cross section protruding to a direction opposite to the second member 14. Further, the adjustment part 22 is provided with an arc shaped corner part 26C which is formed having a thickness larger than a thickness of the other portion of the adjustment part 22. The structure reduces a difference of thermal deformation amounts between the first member 12 and the second member 14 occurring when the joint structure 10 is heated while inhibiting increase of the weight of the joint structure 10.SELECTED DRAWING: Figure 2
