摘要: A composite reinforcing bar is formed from a series of inner rovings with first and second helical wrappings at least one roving wrapped around the in opposed directions wrapping resin permeated therethrough. The structure to allow torsional bending sufficient be wound form coil times an axis right angles length bar. forwarded into rotating winding frame by posts vertical rotation axis. held place while removed for transporting remote location. At location placed similar pulled cut required length.
