    摘要: A propeller for a prop-jet engine having a propellor blade formed as a hollow shell member whose outer surface has an aerodynamic blade profile, the propellor blade being secured to a rotor via an adjustment pin. The hollow shell member is internally braced partly along its radial length by a flexible spar secured to the pin and made of thermoplastic material. The flexible spar is hollow and receives a metal spar hich is fixed to the pin and is given flexibility in bending by the provision of a slot therein.

    摘要: 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.

    摘要: A composite laminate or layer structure includes a substrate (2) and a cover layer (4) bonded thereon. The substrate is made up of at least one layer (3) of fiber-reinforced synthetic material. The cover layer includes at least one layer (5) of metal fibers and/or threads (6), and a metal sheet (7) forming the outer surface skin (8) of the layer structure. The metal sheet is bonded by soldering or sintering onto the metal fibers and/or threads (6), while the layer of metal fibers and/or threads in turn is bonded to the underlying fiber-reinforced synthetic material (3) by being mutually and integrally permeated by a synthetic resin matrix and bonding material. Also, the metal fibers and/or threads (6) may be intermeshed with the fibers of the synthetic material (3). To provide improved bonding at both opposite sides thereof, the layer (5) of metal fibers and/or threads (6) has a lower porosity on the side adjoining the metal sheet, and a higher porosity on the side adjoining the fiber-reinforced synthetic material (3) of the substrate.
