    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.

    摘要： A method for forming a ring structure having a high volume fraction of a filament reinforcement within a metal matrix is disclosed. The ring structure is formed by consolidating a set of nested rings each of which has a high volume fraction of the filamentary reinforcement therein. The nesting is done to provide a clearance between the rings of the nest of about 2 or 3 mils. The nested rings are enclosed within a HIPing can and the structure is HIPed at about 15 ksi and 1000.degree. C. for over an hour. A single superring structure results from the HIPing.

    摘要： A composite material (20) comprises a matrix layer (21) having a plurality of interspersed reinforcing whiskers (23) and a plurality of continuous reinforcing fibers (25) embedded within the matrix layer (21). The preferred embodiment includes a matrix layer (21) which may be a ceramic, intermetallic or metallic material having interspersed reinforcing whiskers (23) upon which a second layer of the matrix (24) having embedded continuous reinforcing fibers (25) is placed, and a third layer (22) of the matrix material having the interspersed reinforcing whiskers (23) on the second layer (24). The composite exhibits improved fracture toughness due to the crack deflection ability of whiskers (23) and crack bridging and fiber pull out due to continuous fibers (25) and minimizes creep associated with known ceramic and intermetallic composites.

    摘要： A method for improved HIPing of filament reinforced metal matrix composite samples is disclosed. The method departs from conventional HIPing practice in that it does not rely on the heating of the HIPing gas in order to increase pressure. Rather, the temperature of the article and of the HIPing gas is first to the HIPing temperature and the pressure of the gas and the pressure on the sample is then raised to the HIPing pressure. Benefits are derived in that a lower level of filament fracture results.
