Abstract

L'invention a pour objet un élément absorbeur d'énergie, en particulier destiné à un ensemble pare-chocs de véhicule, réalisé à partir de panneaux « roll-bond », de préférence de type biface, en alliage d'aluminium.De préférence les zones gonflées se répartissent de façon régulière non directionnelle sur le panneau sous forme de « pastilles », par exemple circulaires ou ovales, correspondant à une structure dite du type « bouilleur ».L'alliage utilisé est de préférence un alliage à durcissement structural de la famille 6000, par exemple du type 6016 à l'état T6.L'invention a également pour objet un procédé de fabrication de ces absorbeurs comportant la réalisation desdits panneaux « roll-bond », les opérations de gonflage après colaminage et mise en forme étant préférentiellement effectuées à l'état T4 dans le cas d'alliages à durcissement structural, et éventuellement l'assemblage pour obtention de structures tubulaires fermées, suivi du traitement thermique de revenu dans le cas d'alliages à durcissement structural.The subject of the invention is an energy-absorbing element, in particular intended for a vehicle bumper assembly, made from “roll-bond” panels, preferably of the two-sided type, made of aluminum alloy. the swollen zones are distributed in a regular non-directional manner on the panel in the form of “pellets”, for example circular or oval, corresponding to a structure known as of the “boiler” type. The alloy used is preferably an alloy with structural hardening of the 6000 family, for example of type 6016 in the T6 state. The subject of the invention is also a method for manufacturing these absorbers comprising the production of said "roll-bond" panels, the inflation operations after co-rolling and shaping being preferably carried out in the T4 state in the case of age-hardening alloys, and possibly the assembly to obtain closed tubular structures, followed by the tempering heat treatment in the case of al age-hardening bindings.
