Abstract
A method of making an elongate, composite-material, hollow rebar structure including (a) forming an elongate, composite-material, hollow core, (b) in association with such forming, preparing along the core's length an elongate, composite-material, core-circumsurrounding, hollow sleeve having inner and outer surfaces, (c) in association with such preparing, creating, unitarily with the sleeve, and in a manner distributed along the length of the sleeve's outer surface, an external-purchase-enhancing structure possessing radial-dimensionality, and (d) bonding the inner surface of the sleeve to the outer surface of the core.
