Patent number: 5866254Abstract: A reinforcement-containing metal-matrix composite material is formed by dispersing pieces of reinforcement material throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture at a sufficiently high rate that the solid metal matrix is amorphous. Dispersing is typically accomplished either by melting the metal and mixing the pieces of reinforcement material into the melt, or by providing a mass of pieces of the reinforcement material and infiltration of the molten amorphous metal into the mass. The metal preferably has a composition of about that of a eutectic composition, and most preferably has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel.Type: GrantFiled: October 15, 1996Date of Patent: February 2, 1999Assignee: Amorphous Technologies InternationalInventors: Atakan Peker, William L. Johnson, Robert Schafer, David M. Scruggs

Patent number: 5853882Abstract: An composite prepreg ply which can be designed to exhibit desired electrical properties without loss of structural integrity or the addition of parasitic weight, and a method of preparing the composite prepreg ply. The composite prepreg ply includes: (i) a low dielectric cloth substrate having a metal layer adherent on both sides thereon, the metal having been selectively removed from at least one portion of at least one side of the cloth, such that there is at least one area of cloth without any metal adherent thereon; (ii) a layer of encapsulant resin material adherent on the metal layer; (iii) a resistive resin layer containing a filler material dispersed in a carrier resin, the resistive resin layer adherent on desired areas the cloth without any metal adherent thereon, and (iv) an impregnating resin covering one or both outermost surfaces of the encapsulant resin material and the resistive resin layer.Type: GrantFiled: August 26, 1997Date of Patent: December 29, 1998Assignee: McDonnell Douglas CorporationInventors: Anne E. Cenedella, Richard E. Sharp

Patent number: 5846655Abstract: A layer of silver-metal oxide, a layer of gold or a gold alloy and, a layer of rhodium or ruthenium are electrolytically produced on a metal base, preferably in the form of a wire. The gold alloy is partially diffused into the silver-metal oxide layer by an annealing process at a temperature between 300.degree. and 900.degree. C. As a result, a low-impedance and burn-up resistant contact coated element is provided for employment in weak current relays.Type: GrantFiled: August 16, 1996Date of Patent: December 8, 1998Assignee: Siemens AktiengesellschaftInventors: Guenther Henning, Ursula Michelsen-Mohammadein, De Marc Vogelaere, Josef Weiser

Patent number: 5814403Abstract: A computer model calculates a critical aspect ratio for a discontinuous fiber composite having fibers dispersed in a matrix. The critical aspect ratio is a function of the elastic modulus and the cohesive energy of the fiber and the matrix. The composite incorporates physical features such as fiber shape features or additives in the fiber or matrix which adjust the elastic modulus and/or cohesive energy of the fiber, of the matrix or both to a value different than the corresponding value for unmodified fiber material or matrix material. These adjustments are selected so that the critical aspect ratio for the material including the modifications will be less than the corresponding critical aspect ratio for the material without the modifications. The resulting composite provides enhanced load sharing between fiber and matrix.Type: GrantFiled: January 28, 1993Date of Patent: September 29, 1998Assignee: Exxon Research and Engineering CompanyInventors: Michael P. Anderson, Liza M. Monette, John P. Dismukes, Shiun Ling, David J. Srolovitz

Patent number: 5814408Abstract: An aluminum matrix composite is provided comprising a preform formed from interwoven mats of graphitized vapor grown carbon fibers. The mats comprise semi-aligned, semi-continuous vapor grown carbon fibers which have been interwoven in situ during growth. The preferred method of producing the composite includes the steps of providing a vapor grown carbon preform and infiltrating molten aluminum into the interstices of the preform by a pressure casting process. The resulting aluminum matrix composite has a thermal conductivity of between about 600 W/m-K and 700 W/m-K and is useful as a component in electronic devices, aircraft, spacecraft, and other thermal management applications.Type: GrantFiled: January 31, 1996Date of Patent: September 29, 1998Assignee: Applied Sciences, Inc.Inventors: Jyh-Ming Ting, Max Laverne Lake
