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.
Un élément de structure armé (10) présente un élément de structure rigide (12) en plastique recyclé dans lequel est enserrée une barre d'armature (16) affleurant sur l'une des faces (12a). L'élément de structure rigide (12) comporte une entaille (14) tournée vers l'intérieur en partant de la face (12a) contre laquelle doit s'exercer la contrainte. Une barre d'armature (16) sur laquelle aucune tension n'a été exercée, est faite d'un matériau aux caractéristiques de résilience et de compressibilité différentes de celles de l'élément de structure (12) enserré et inamovible dans l'entaille (14). La barre d'armature (16), dont la forme est complémentaire de celle de l'entaille (14), est maintenue en place par la densité de l'élément de structure rigide (12) et par des fixations telles que des vis. Ce procédé permet de combiner deux matériaux dont aucun ne possède assez de résistance, de rigidité ou de mémoire de forme pour créer un assemblage de composants durable et peu coûteux, mais aux qualités mécaniques supérieures à celles de chacun des matériaux de départ.
