<p>A reinforced structural member (10) comprising a solid structural member (12) of recycled plastic having a reinforcing bar (16) inserted therein, extending inwardly from one surface (12a). A notch (14) is formed in the solid structural member (12) extending inwardly with respect to the surface (12a) against which force is to be exerted. An untensioned reinforcing bar (16) formed of a material having characteristics of resilience and compressibility different from that of the structural member (12) is inserted and locked into the notch (14). The reinforcing bar (16) is complementary in shape to the notch (14), and is held in place by the density of the solid structural member (12) and fasteners such as screws. In this way, two dissimilar materials, neither of which alone has sufficient strength, rigidity, or "memory" can be combined to create a durable, inexpensive set of components which substantially exceed the mechanical qualities of either material by itself.</p> |
