Abstract
A bonded structure includes a first fiber part (12) and a second fiber part (14) arranged between a first member (10) and a second member (20). The first fiber part (12) and the second fiber part (14) are bonded so as to connect the first member (10) and the second member (20) to each other. The first fiber part (12) and the second fiber part (14) are arranged so that the fibers constituting the first fiber part (12) and the second fiber part (14) are oriented in a direction from the first member (10) toward the second member (20).
Claims5
A bonded structure in which a first member and a second member are bonded together in an opposing state, the bonded structure comprising a crack growth prevention part arranged between the first member and the second member,
- wherein the first member has a first bonding surface and the second member has a second bonding surface,
- wherein the crack growth prevention part is provided so as to connect the first bonding surface and the second bonding surface to each other,
- wherein the crack growth prevention part includes fibers and is arranged so that the fibers are oriented in a direction from the first bonding surface toward the second bonding surface,
- wherein the crack growth prevention part includes a first fiber part and a second fiber part,
- wherein the first bonding surface and the second bonding surface each include a first region, a second region, and a third region provided between the first region and the second region,
- wherein the first fiber part is provided so as to connect the first region of the first bonding surface and the second region of the second bonding surface to each other,
- wherein the second fiber part is provided so as to connect the second region of the first bonding surface and the first region of the second bonding surface to each other,
- wherein the first fiber part and the second fiber part are arranged to cross each other when the third region is seen from between the first member and the second member,
- further comprising a reinforcement part and a bonding part arranged between the first member and the second member,
- wherein the first fiber part and the second fiber part each include a continuous region and a strip-shaped region,
- wherein the continuous region of the first fiber part is bonded to the first region of the first bonding surface, the continuous region of the second fiber part is bonded to the first region of the second bonding surface, and the bonding part is arranged between the continuous region of the first fiber part and the continuous region of the second fiber part, and
- wherein the strip-shaped region of the first fiber part and the strip-shaped region of the second fiber part are directly bonded together, slits are provided so that a plurality of strip-shaped regions are formed along a fiber orientation direction, the plurality of strip-shaped regions are alternately bonded to the second region of the first bonding surface and the second region of the second bonding surface, and the reinforcement part is arranged between the bonded strip-shaped regions.
