Publication number: 20020114928Abstract: This invention provides a composite material having a matrix of structural material containing embedded zones of soft elastic material and zones of solid relatively high density material within the soft elastic material. By selecting a particular resonance frequency for the subunits of soft elastic material and solid high density material, frequencies just lower than the resonance frequencies will be unable to propagate through the material and be strongly reflected or absorbed. Such material may be used in the manufacture of filters or shields against particular target frequencies. Subunits having a variety of resonance frequencies may provide a broader range of frequencies that the material may shield.Type: ApplicationFiled: April 3, 1998Publication date: August 22, 2002Inventors: PING SHENG, RONGFU XIAO, WEIJIA WEN, ZHENG YOU LIU

In 25 to 60% of the sheets, said fibers are oriented at 0%±5° with respect to the longitudinal direction of the part, when the matrix is based on aluminum. In the other sheets, the fibers are then oriented between ±20 and ±40° with respect to said direction. When the matrix is based on magnesium, the ultra-high modulus fibers are oriented at 0°±5° in at least 90% of the sheets. This gives a high rigidity and high stability in the indicated direction, which favors applications in the space industry.Type: GrantFiled: November 13, 1998Date of Patent: March 6, 2001Assignee: Aerospatiale Societe Nationale IndustrielleInventors: Laetitia Billaud, Jocelyn Gaudin, Martine Nivet Lutz, Joël Poncy

Patent number: 6183877Abstract: This composite consists of an aluminum-alloy matrix containing by volume percent, 0.4 to 8.8 alumina, 1 to 4.4 carbon or graphite and 0.5 to 20 nickel-bearing aluminide. The alumina particles have an average size between 3 and 250 &mgr;m and the carbon and graphite particles have an average size between 10 and 250 &mgr;m. The composite is cast by stirring alumina and carbon or graphite contained in a molten aluminum or aluminum-base alloy to form a molten mixture. The molten mixture is cast directly from a temperature above the liquidus of the matrix alloy. While solidifying, carbon or graphite particles delay or hinder the settling of alumina to create a more uniform composite structure. The resulting composite structure contains an aluminum-base alloy, alumina, carbon or graphite and nickel-bearing aluminide dispersoids.Type: GrantFiled: August 20, 1997Date of Patent: February 6, 2001Assignee: Inco LimitedInventors: James Alexander Evert Bell, Pradeep Kumar Rohatgi, Thomas Francis Stephenson, Anthony Edward Moline Warner
