Abstract

1349383 Coated products SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 4 June 1971 [5 June 1970] 19094/71 Heading B2E [Also in Divisions B7 and Fl] The resistance of a surface to erosion is improved by (a) applying to the surface at least one layer of a composite material comprising a plastics binding agent containing 30-70% by volume of threads or fibres having a boron, boron carbide or silicon carbide surface, (b) eliminating the superficial part of the matrix by means of a pre-erosion of the sand-blasting type, and (c) coating the surface thus obtained with a polyurethane binder containing 15-60% by volume of micronised particles having surfaces of boron, boron carbide or silicon carbide. The surface to be protected may be of a helicopter blade comprising a metal core or of a compressor blade formed of epoxy-resin impregnated carbon fibres or glass fibres. In the former case, the layer(s) of composite material are glued to the metal surface whereas in the latter case, application of the composite material is effected in the mould where the compressor blade is being formed.
