Title:
PIPE STRUCTURE AND TRUSS STRUCTURE, AND ARTIFICIAL SATELLITE USING SUCH STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2019/225294
Kind Code:
A1
Abstract:
The present invention is provided with: a pipe 5 made of fiber-reinforced plastic; damp-proof foils 11, 12 that cover the outer circumferential surface and the inner circumferential surface of the pipe 5, respectively; and a metal intermediate member 4 that is fitted to an end of the pipe 5, wherein ends of the damp-proof foils 11, 12 are tightly sandwiched between the pipe 5 and the intermediate member 4. This configuration ensures prevention of moisture absorption into the FRP pipe, and enables preventing contraction due to moisture removal in outer space, thereby making it possible to obtain a pipe structure having excellent dimensional stability.
