Abstract
The invention relates to a composite material having a substrate, which contains at least one fiber layer, and a cover layer, which adjoins the substrate and which, at least adjacent to the at least one fiber layer, contains metallic fibers and/or threads. The at least one fiber layer of the substrate and the metallic fibers and/or threads of the cover layer being saturated with binder and, as a result, the substrate and the cover layer are formed together or connected. Metallic, ceramic or glass-type particles are embedded in the cover layer in the area of the metallic fibers and/or threads. Preferably, the particles may be one or more or a combination of TiC, TiN, TiAl, Fe, steel, Ni, Si, metal alloys, diamond, or glass. In addition, the invention provides a process for manufacturing a composite material and articles of manufacture comprising the composite material, especially for rotor blades or propellers. The composite material and products comprising it display improved abrasion and erosion resistance and are protected from electrical damages.
