Document Type and Number:
WIPO Patent Application WO/2013/030960
Kind Code:
A1
Abstract:
Provided is a fastening structure for fixing a component to a composite material, more specifically for fixing a composite material having a sandwich structure in which a core material is disposed between surface materials and a component to be fastened, without using an adhesive layer. The fastening structure is simple and easy to construct. The fastening structure uses a mechanical fastening means having excellent heat-insulating properties and excellent reliability. The fastening structure for fixing a component to a composite material uses a bolt and nut (1, 2) to fasten and fix a component (20) which is the material to be fastened to a composite material (7) in which a core material (6a, 6b) is disposed between upper and lower surface materials (5a, 5b). On the inside of the composite material (7) where the bolt and nut are to be disposed an insert body (100) formed of a thin metal plate is arranged in a state of contact with each of the upper and lower surface materials, and on the outside of the composite material (7) where the insert body is disposed, washers (3, 4) are arranged in a state of contact with the external surface of the surface material. The bolt and nut extend through the composite material (7), the insert body (100) and the washers (3, 4) so as to fasten and integrally fix the component (20) to said composite material (7).
