PREPREG FOR PREVENTING DIFFERENT LEVELS, MANUFACTURING METHOD OF TUBULAR BODY USING THE SAME AND TUBULAR BODY

摘要

PROBLEM TO BE SOLVED: To provide prepreg for preventing different levels and deviation thickness derived from influence at the beginning and the end of sheet winding in molding of a tubular body obtained by sheet wind molding, and to provide the tubular body having a smooth surface. SOLUTION: In a molding method of the tubular body obtained by the sheet wind molding method that end portions of a prepreg sheet are laminated sliding in a peripheral direction so that the end portions of the prepreg sheet are not piled up in a thickness direction, the method comprises arranging to join the both wind end portions of the laminated prepreg sheet to the prepreg for preventing the different levels comprising a fabric prepreg having a width of 2-20 mm, a resin content of 50-90 wt.% and a thickness of 0.04-0.10 mm.
