FIRE-PROTECTED COMPOSITE STRUCTURE

摘要

A fire-protected composite structure (2, 6) comprises a composite component (32, 62) having a first surface (34, 64) and a hot sprayed metallic layer (36, 66) is deposited on the first surface ((34), (64). In the event of a malfunction which generates a flame, the outer surface( 34, 64) is offered some fire protection by the hot sprayed metallic layer (36, 66). The layer (36, 66) acts as a physical barrier stopping the flame from directly acting on the composite material and also, because the metal or metal alloy of the layer (36, 66) has good thermal conductivity, the layer (36, 66) conducts the heat of the flame away from the point of impingement of the flame on the composite material, thus stopping or slowing the thermal degradation of the matrix (resin) of the composite material.
