This invention relates to extruded composite materials specifically focusing on the increasing load bearing capacity and the overall strength of composites. Injectable conformable structural core materials are used to replace foam cells inside extruded composite materials thereby increasing the overall load bearing stability and strength. The core materials are tailored to have a desired CTE with respect to the structural materials. The core materials may also incorporate fibers and solid structural fillers for increasing the strength of the composite member. The objective is to enable composite materials to have the highest structural load bearing capability possible so that these technologies can be used as the replacement of wood, in aerospace applications and for other purposes.

L'invention concerne des matériaux composites extrudés destinés essentiellement à augmenter la capacité de charge et la résistance globale des composites. On utilise des matériaux à noyau structurel injectables et adaptables pour remplacer les cellules de mousse à l'intérieur des matériaux composites extrudés, ce qui permet d'augmenter la stabilité et la résistance de charge générale. Les matériaux à noyau sont conçus pour avoir un coefficient d'expansion thermique en rapport avec les matériaux structurels. Les matériaux à noyau peuvent également intégrer des fibres et des charges structurelles solides destinées à augmenter la résistance de l'élément composite. L'objectif est de permettre aux matériaux composites de supporter la capacité de charge structurelle la plus élevée possible, de sorte qu'il est possible d'utiliser ces technologies pour remplacer le bois, dans des applications aérospatiales et à d'autres fins.
