PIPE AND PRODUCTION METHOD FOR PIPE

摘要

A pipe (1) is provided with: a reinforcing fiber structural body (22) having a tubular shape; and a matrix resin (29) that, by covering the inner side and the outer side of the reinforcing fiber structural body (22), said inner side being the central axis side of said reinforcing fiber structural body (22), forms in conjunction with the reinforcing fiber structural body (22) a tubular pipe main body (2) having said central axis as the center thereof. The outer surface of the end section of the pipe main body (2) has a main body-inclined surface, the diameter of which gradually decreases with increasing proximity to an end surface. When the pipe main body (2) is connected to another pipe main body, the main body-inclined surface is joined with a substantially tubular coupling. The section of the pipe main body (2) that is located in the vicinity of the main body-inclined surface in the reinforcing fiber structural body (22) is configured from a plurality of fiber bundles (241) that extend in parallel along the central axis. As a result, shear fractures in which the fiber bundles in the reinforcing fiber structural body (22) are stretched tight and pulled out from the pipe main body (2) are prevented from occurring at the main body-inclined surface, thereby improving the shear strength at the main body-inclined surface.
