    摘要： A composite metallic preform tape for use as laminae in the manufacture of metallic composite articles is made from a pair of metallic foils and high strength, high modulus filaments aligned between the foils. One form of the method involves first coating either the foil inner surfaces or the filament outer surfaces, or both, with a thin, non-metallic adhesive bonding material which will decompose leaving substantially no residue upon heating at a temperature below that at which the foil and filaments will melt, and preferably below that at which they will bond together. The foil and the aligned filaments are themselves aligned and, in a continuous form of the method, are moved at substantially the same rate and in the same direction so that the coated surface is between the foil and filaments. At the same time, the foil and filaments are pressed toward one another with a force sufficient to adhesively bond together the foil and filaments and to plastically deform the foil around at least a portion of substantially each filament.In a preferred form, at least one plastically deformable, strippable outer film is applied for protection and, if desired, for a quality control record. Deformation of the foils around at least a portion of substantially each filament results in an article having a sandwich construction including centrally aligned filaments maintained in spaced apart relationship.

    摘要： A thermal bed screen pack is fabricated from stacked wire mesh discs, the compressed pack having a brazed outer periphery that is threaded so that the pack may be screwed into position adjacent an injector of, for example, a gas generator device. The thermal screen pack is then mechanically interlocked with the threaded grooves in the gas generator housing, thus inhibiting compaction and settling.

    摘要： A process for increasing the whisker content in a matrix comprises the steps of aligning and depositing reinforcing whiskers on a metal substrate, stacking layers of these substrates into a preform assembly, diffusion bonding this assembly to consolidate the preforms into a composite foil and heating the composite 50* to 100* F. above its melting point, while applying a slight pressure thereto. Consequently, some of the molten matrix is forced out from the edges of the composite. This results in a thinner composite foil having a higher whisker concentration and consequent higher ultimate tensile strength.

    摘要： A process for the preparation of a fiber reinforced metal matrix composite comprising fibers embedded in a metal in which the process comprises forming a body with a layer of aligned fibers between at least two layers of metal foil and densifying said layers wherein the layer of aligned fibers comprises metal particles interposed between individual fibers, the metal particles being compatible with the metal foil. A preform for a fiber reinforced metal matrix composite is also claimed which comprises a resin and a layer of aligned fibers, the layer having metal particles interposed between adjacent fibers and the layer and particles being bonded together with the resin.
