Abstract
A rebar structure for concrete reinforcement may include an elongate tubular central wall portion having an inside surface and an outside surface. The central wall portion may be formed circumferentially around a core axis and may include glass or carbon fibers mostly being oriented longitudinally parallel to the core axis. The rebar structure may include an inner wall portion bonded to the inside surface of the central wall portion. The inner wall portion may include glass or carbon fibers and may have a higher percentage of fibers oriented non-parallel to the core axis as compared to the central wall portion.
