Abstract

PURPOSE:To obtain a lock bolt excellent in strength, easy to cut, having electric insulation, hard to rust, low in weight and cost by a method wherein a circular coating having a spiral projection is provided by specific resin about the outer circumferential surface of core material obtained by binding a reinforcing fiber bunde with resin. CONSTITUTION:The outer circumference of the core material 1 obtained by binding reinforcing fibers integrally with thermosetting resin is coated circularly with a thermoplastic resin layer 9 to obtain a coaxial structure and the spiral projection 3 is provided on part of the coating. Both thermosetting resin and thermoplastic one have common monomer component to each other, are bound along their joint boundary and almost all of the external force is supported by the core material 1.
