Abstract: The pipe structure according to the present invention includes: a fiber-reinforced plastic pipe 5; moisture-proof foils 11, 12 which individually cover an outer circumferential surface of the pipe 5 and an inner circumferential surface thereof; and an intermediate part 4 which is made of metal and fitted to an end of the pipe 5, wherein end portions of the moisture-proof foils 11, 12 are tightly sandwiched between the pipe 5 and the intermediate part 4. This configuration reliably prevents an FRP pipe from absorbing moisture, and thus, prevents the FRP pipe from shrinking due to moisture exhaustion in outer space, whereby it is possible to obtain the pipe structure having excellent dimensional stability.

Abstract: A honeycomb core includes carbon fiber having four or more different fiber directions, and when a ribbon direction is set as an X axis direction, a cell width direction is set as a Y axis direction, and a direction that is orthogonal to the ribbon direction and the cell width direction is set as a Z axis direction. A condition in which angles formed by the X axis direction and the respective fiber directions of the carbon fiber are set at −45 degrees, 0 degrees, 45 degrees, and 90 degrees is set as a reference condition. The respective fiber directions are rotated from the reference condition by a fixed rotation angle so that none of the fiber directions are parallel to the X axis direction.
