Abstract
Damping skin for protecting composite parts includes a composite material having at least two superposed layers, namely a first layer formed from the juxtaposition of hollow spheres, which is intended to be applied and fixed, either directly or indirectly, to the surface of the part to be protected and a second layer covering the first and formed from a wall made of a material having plastic deformation properties.
Claims12
A damping skin system for protecting composite parts, said damping skin system comprising:
- a substrate comprised of a first composite material and having a surface, said first composite material being comprised of a first structural component and a first resin;
- a skin comprised of a second composite material and a wall layer, said second composite material being comprised of a second structural component and a second resin,
- wherein said second composite material is a first layer and said wall layer is a second layer, said first layer and said second layer being superposed, said second layer covering said first layer,
- wherein said second structural component is comprised of a juxtaposition of hollow spheres applied and fixed to said surface, and
- wherein said second layer is comprised of a moldable and resilient material, said first composite material having more mechanical resistance than said first layer.
