A reinforced formed part having longitudinal or cross-sections of different form or size, as necessary, having a hollow external formed part and a metal foam filling, produced by foaming the foam material in the formed external formed part with a closed cell foam with high resistance to deformation, the foam filling being at least in part in contact with the external formed part filling the internal cavity of the hollow external formed part, at least in part, and improving the mechanical resistance of the external formed part to deformation, as well as a process to produce the formed part, where a hollow section is produced by a forming process as known per se and a foam body is then introduced into the formed part in such a way that the foam body, at least in part, makes contact with the hollow part and is attached in the hollow part by snug fit or by a known attachment method, as well as the use of the formed part, as described herein, as a supporting part in scaffolding, framework, for example, in construction, in vehicle building for air, land and water craft and furniture.

L'invention concerne une pièce moulée renforcée dont la longueur et/ou la section peut varier sur le plan de la forme et/ou des dimensions. Cette pièce moulée comporte une pièce moulée extérieure creuse (12) et un remplissage en mousse (14) à alvéoles ouvertes ou fermées, hautement résistante à la déformation. Cette mousse est au moins en partie adjacente à la pièce moulée extérieure. Elle remplit au moins en partie la cavité de la pièce moulée creuse (12) et améliore la résistance mécanique de la pièce moulée extérieure contre la déformation. L'invention concerne également un procédé de fabrication de ladite pièce moulée, selon lequel une pièce creuse est fabriquée par un procédé de moulage déjà connu, et ensuite un corps en mousse est inséré dans cette pièce creuse de telle façon que le corps en mousse soit au moins partiellement plaqué contre la pièce creuse et soit fixé dans la pièce creuse par un ajustement fin ou encore par un procédé de fixation connu. L'invention concerne enfin l'utilisation de ladite pièce moulée, conformément à une des revendications précédentes, comme partie porteuse dans des échafaudages, des charpentes par exemple dans le bâtiment, dans la construction d'aéronefs, de véhicules terrestres et de navires et dans l'industrie du meuble.
