摘要： A fiber reinforced plastic pipe is provided to prevent it from being damaged and make full use of its practical performance when the fiber reinforced plastic pipe, reduced in thickness and increased in diameter by pultrusion process, is reduced in the circumferential direction and inserted into a metal pipe. The fiber reinforced plastic pipe, reduced in thickness and increased in diameter by pultrusion process, includes a fiber bundle spun and aligned in the longitudinal direction, and circumferential reinforced fiber sheet provided at least on one of the outer and inner surface layers. The circumferential reinforced fiber sheet is inserted into the metal pipe to form a power transmission shaft such as an intermediate shaft for use with a propeller shaft or a drive shaft.
