Title (EN) STRUCTURAL AIRCRAFT PANEL MADE OF COMPOSITE MATERIAL INCORPORATING PROTECTION AGAINST HIGH-ENERGY IMPACTS
(FR) PANNEAU STRUCTURAL D'AÉRONEF EN MATÉRIAU COMPOSITE INCORPORANT UNE PROTECTION CONTRE LES IMPACTS À HAUTE ÉNERGIE
Abstract: front page image
(EN)The invention provides a structural panel (2) consisting of a stratified composite material comprising one face exposed to impacts and further comprising a layer consisting of a hyper-elastic material (3) bonded adhesively to its other face. In accordance with this embodiment, debris striking the exposed face of this composite panel will have some of its energy dissipated by the local rupture of the composite skin, while the rest of the energy is absorbed by the deformation of the layer of hyper-elastic material which captures the debris and expels it again.
(FR)L'invention propose un panneau structural (2) constitué d'un matériau composite stratifié et comprenant une face exposée à des impacts, comprenant en outre une couche constituée d'un matériau hyper-élastique (3) rapportée par collage sur son autre face. Selon ce mode de réalisation, un débris venant impacter la face exposée de ce panneau composite verra une partie de son énergie dissipée par la rupture locale de la peau en composite, l'énergie restante étant absorbée par la déformation de la couche de matériau hyper-élastique qui retient le débris et le repousse vers l'extérieur.
