Abstract

1309519 Composite metallic sheet material PFIZER INC 14 July 1971 [17 March 1971] 33145/71 Heading E1K [Also in Division B3] A method of making a clad reinforced composite comprises distributing reinforcing material between matrix metal sheets 14 to form a core, enclosing the core between a pair of metal plates 18 to form an envelope, bonding the edges of the envelope, evacuating the envelope and applying heat and pressure to consolidate the reinforcing material, the matrix metal and at least one of the metal plates. Alternate layers of aluminium foil and boronon-tungsten filaments are enclosed in an envelope of stainless steel/aluminium alloy, which is closed and evacuated to a vacuum of a few millimeters of mercury. The composite is held under a pressure of 2000-4000 p.s.i. at 850‹-950‹F for 5-15 minutes and cooled slowly in a holding oven. Below 500‹F cooling is carried out more rapidly. Following this procedure, silicon carbide coated graphite ribbons are consolidated in an aluminium alloy matrix clad with a stainless steel/aluminium alloy envelope. In an alternative embodiment silicon carbide-on-tungsten filaments are embedded in a titanium alloy matrix in stainless steel/alumium cladding. This combination is heated to 1350‹-1450‹F at about 4,000- 6,000 p.s.i. for 10-15 minutes. The composite is then cooled slowly to below 750‹F. Other reinforcements comprise graphite, beryllium, boron, silicon carbide-on-boron, silicon carbide, aluminium silicate, boron nitride-on-boron boron nitride, silicon carbide-on-boron carbide, aluminium oxide, stainless steel, nickel alloyon-niobium, and tungsten. These reinforcements may be used with certain combinations of aluminium, copper, cobalt, magnesium, nickel, tantalum or titanium matrices with aluminium, copper, aluminium/chromium, niobium/tantalum alloy, tantalum alloy, titanium or brazing alloy cladding. When only one side of the reinforced composite is clad, one side of the envelope is made from mild steel plate suitably coated to prevent bonding to the matrix. The plate is subsequently stripped from the composite after cutting away the bonded edges of the envelope. The strippable plate may be pre-shaped to act as a former and the composite may be shaped by pressing, rolling, gas-pressure bonding and the like. The composite may be attached to other structures by welding, rivetting, friction or adhesive bonding, either by adhesives or brazing. It may also be protected by the application of a glassy coating or by electroplating, sputtering, anodic treatment or the like. The clad composite has a low mass and is suitable for use in moving machine parts. It may also be used in the construction of rocket nozzles, turbines, integral fuel tanks in aircraft wings, rocket fuel tanks, missile skins and in chemical plant where adaptability to high temperatures and/or large pressures in combination with either chemical inertness or catalysis is desired.
