<p><P>PROBLEM TO BE SOLVED: To prevent the unwinding of a prepreg, without deteriorating the lightweight nature of a tube made of a fiber-reinforced resin and thus to enhance the strength thereof and the productivity therefor. <P>SOLUTION: The method comprises the process of winding a bias prepreg 21 or 22, a straight prepreg 23, 25, 27 or 28 and a hoop prepreg 24 or 26 on a core material each at least by one sheet. Of the hoop prepreg 24 or 26 at least one is in advance laminated/tightly attached onto a base prepreg consisting of the bias prepreg 21 or 22 or the straight prepreg 25 or 27, to form a laminate A1 or A2, and by winding the laminate A1 or A2 the hoop prepreg 24 or 26 is wound integrally with the base prepreg 25 or 27. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
