FRP TUBULAR BODY AND ITS METHOD OF PRODUCTION

摘要

A production method for an FRP cylindrical body, characterized by comprising the steps of disposing a resin diffusion medium and a reinforcing fiber base material on the outer or inner periphery of a cylindrical or sold core, covering the medium and the base material with an airtight material before vacuumizing the inside, and injecting resin for diffusion in a surface direction of the medium and for impregnation into the base material; an FRP cylindrical body characterized in that an FRP layer and a resin diffusion medium are integrated with each other concentrically; and an FRP cylindrical body comprising two or more peripherally-split members which are integrally joined; whereby it is possible to produce even long or large-diameter FRP cylindrical bodies easily and at low costs.
