Abstract (en)
[origin: WO2008128314A1] A composite reinforcing bar is formed by providing a reinforcing material supply of fiber strands rovings; a resin supply bath, and a puller for pulling the resin-impregnated reinforcing material through the resin bath. The reinforcing fibers include a series of inner rovings longitudinal to the bar with a first and a second helical wrappings of at least one roving wrapped around the inner rovings in opposed directions of wrapping. The resin is permeated through both the inner rovings and through the wrapped rovings to the outer surface where the inner rovings having parts thereof between the first and second wrapped rovings exposed and bulged outwardly by tension applied by the wrappings during curing with the bulged parts defining components of the outer surface portion of the bar which are thus rough and exposed for engaging a material to be reinforced so as to transfer longitudinal loads between the material to be reinforced and the inner rovings.
