Abstract

Official abstract text for this publication.

A fiber reinforced plastic bolt(FRP) and a method for producing the same are disclosed. The FRP bolt is useful in the industrial areas which require a bolt having electric-insulation, anti-corrosive, thermal-insulation, and non-magnetic properties. The method for producing the FRP bolt includes the steps of: winding a prepreg around a surface of an internal body, wherein the internal body includes a first reinforcing fiber which is unidirectionally aligned along the axis of the bolt, and a synthetic resin which is impregnated into the first reinforcing fiber, and the prepreg includes a second reinforcing fiber and a thermosetting resin which is impregnated into the second reinforcing fiber; forming a fiber reinforced plastic round bar by heat-hardening the prepreg; and forming a screw thread on the surface of the fiber reinforced plastic round bar.

First claim
