Shock absorbing coating for rigid surface

摘要

The coating is used on items (2) such as vehicle chassis. It is a composite coating (1) and made up of a layer of viscoelastic material (3) together with an external constraining layer (4,5,6). The constraining layer has a core (4) of material. This core material is sufficiently flexible in its initial state so as to not prevent it being applied to structures with a complex shape. It becomes rigid under the effects of heat. This material is also able to expand and its volume increases as it is heated.
