Composite protection for revealing damage to a core in a vehicle such as an aircraft

摘要

The composite structure for protecting a main core comprises a laminated surface covering having a rigid protective layer and an elastomeric member. A damage tell-tale is inserted between the rigid protective layer and the elastomeric member. The composite structure thus serves both to protect the core and to reveal damage suffered by the core. The structure is applicable, for example, to protecting a structural element of a vehicle such as a helicopter.
