MANUFACTURE OF FRP TUBULAR BODY

PROBLEM TO BE SOLVED: To manufacture an FRP tubular body having no creases and a small rate of voids by dry-removing at least a part of an organic solvent in impregnated resin, and further winding a sheet plate on a layer with resin-impregnated fiber wound therearound formed on a mold before executing heat-compression molding. SOLUTION: Solid heat resistance resin is dissolved in an organic solvent to be made into liquid to then be impregnated in continuous fiber, and thereafter at least a part of the organic solvent in the impregnated resin is dry-removed after this is impregnated In the continuous fiber, and after or before the resin impregnated fiber is wound on the mold, and further a sheet plate is wound on a layer with resin-impregnated fiber wound therearound formed on the mold is subjected to heat-compression molding. For example, by the use of an organic solvent solution of carbon fiber and polyimide resin, a peripherally wound cylinder is manufactured. Namely, after forming a wound layer 2 by being wound circumferentially on the mold 1 while making impregnation in fiber, e.g. a solvent is removed through heating at 80 deg.C, and an aluminum sheet plate 3 is wound therearound to be lapped at its seam S; subsequently a vacuum pack is mounted thereover before conducting compression heating.
