A re-bar (reinforcing rod) for concrete comprises an inner rod of a first material, and an over-wrap of a second material. The over-wrap is structurally or functionally discontinuous relative to the inner rod. In another aspect, the present invention relates to a reinforcing rod comprising a composite of at least two materials, at least one of which is present in structurally discontinuous lengths. The composite comprises a polymer matrix having embedded therein structurally discrete meso-rods of length with radius r m, ultimate and tensile strength .delta.um the frictional shear stress between a meso-rod and the polymer matrix being represented by ~m, wherein (see formula I)
