Definitions

  • the invention relates to a material which comprises a metal matrix composite reinforced with an appropriate amount and type of reinforcement.
  • the matrix metal can be any metal which is capable of desirably interacting with the reinforcement.
  • the metal matrix composite material has applications in environments which experience resonant vibrations. This material ameliorates undesirable resonant vibrations.
  • drum-type brake rotors wherein a friction material contacts a brake drum.
  • the interface between the friction material and brake drum also may cause undesirable resonance to develop and thus, in a similar manner, result in a transmission of undesirable noise.
  • undesirable resonant vibrations can occur in virtually any environment where moving parts are contacted with each other.
  • Additional examples of automotive applications would include transmissions, drive shafts, gears, alternators, generators, engines, wheels, hubs, etc. Each of these areas are also subjects of the present invention.
  • other apparatus that have moving parts that are also the subject of the present invention include electric motors, railway engines and railway cars, hydraulic motors, bearing assemblies, etc.
  • Copper refers to the commercial grades of the substantially pure metal, e.g. , 99% by weight copper with varying amounts of impurities contained therein. Moreover, it also refers to metals which are alloys or intermetallics which do not fall within the definition of bronze, and which contain copper as the major constituent therein.
  • Filler is intended to include either single constituents or mixtures of constituents which are substantially non-reactive with and/or of limited solubility in the matrix or parent metal and may be single or multi-phase. Fillers may be provided in a wide variety of forms, such as powders, flakes, platelets, microspheres, whiskers, bubbles, fibers, particulates, fiber mats, chopped fibers, spheres, pellets, tubules, refractory cloths, etc. , and may be either dense or porous.
  • Filler may also include ceramic fillers, such as alumina or silicon carbide, as fibers, chopped fibers, particulates, whiskers, bubbles, spheres, fiber mats, or the like, and coated fillers such as carbon fibers coated with alumina or silicon carbide to protect the carbon from attack, for example, by a molten aluminum matrix metal. Fillers may also include metals.
  • ceramic fillers such as alumina or silicon carbide, as fibers, chopped fibers, particulates, whiskers, bubbles, spheres, fiber mats, or the like
  • coated fillers such as carbon fibers coated with alumina or silicon carbide to protect the carbon from attack, for example, by a molten aluminum matrix metal.
  • Fillers may also include metals.
  • Figure 1 shows the damping behavior of silicon carbide reinforced aluminum metal matrix composite as a function of reinforcement content.
  • metal matrix composite bodies There are numerous techniques which currently exist for forming metal matrix composite bodies. It is expected that many of these techniques can result in a desirable volume percent of particulate reinforcement being present in the matrix metal of a composite body. However, it should be understood that lesser volume percents of other reinforcements such as, for example, platelets, fibers or whiskers, when combined with a desirable matrix metal, could also produce desirable noise dampening effects.
  • the two particularly preferred methods for forming metal matrix composites include the process known as the PRIMEX* M Pressureless Metal Infiltration Process, which is set forth in numerous patents assigned to Lanxide Technology Company, LP, as well as the self-generated vacuum process, which is also set forth in numerous patents assigned to
  • Figure 1 shows the damping behavior of a metal matrix composite wherein the reinforcement is a particulate silicon carbide and the matrix metal comprises aluminum.
  • the technique utilized to measure the damping behavior of the composites measured in Figure 1 was determined using the flexural resonant frequency Zener Band Width Method. This method is well known and can be found in the publication by G. Zener, Elasticity and An Elasticity of Metals. (University of Chicago Press, 1948).
  • the particulate silicon carbide in the composite of Figure 1 was comprised of 500 grit in some cases and a mixture of 220 grit and 500 grit in other cases .
  • the aluminum matrix metal comprised an aluminum-silicon-magnesium alloy.

Abstract

L'invention concerne un matériau comprenant un composite à matrice en métal renforcé par un matériau de renforcement d'une quantité et d'un type approprié. Le métal matriciel peut être n'importe quel métal capable d'avoir une interaction avantageuse avec le matériau de renforcement. Le matériau composite à matrice en métal présente des applications dans des environnements soumis à des vibrations résonnantes. Ce matériau contribue à réduire les vibrations résonnantes indésirables.
