Publication number: 20200299815Abstract: A metal matrix composite is provided, including a metal, inorganic particles, and discontinuous fibers. The inorganic particles and the discontinuous fibers are dispersed in the metal. The metal includes aluminum, magnesium, or alloys thereof. The inorganic particles have an envelope density that is at least 30% less than a density of the metal. The metal matrix composite has a lower envelope density than the matrix metal while retaining a substantial amount of the mechanical properties of the metal.Type: ApplicationFiled: November 29, 2016Publication date: September 24, 2020Inventors: Gareth A.

Patent number: 8895856Abstract: A compression connector and assembly include an elongated, interiorly hollow tube, and at least one tubular sleeve, the tube including a first material exhibiting a first axial extrusion rate and the sleeve including a second material exhibiting a second axial extrusion rate, wherein the sleeve wall thickness is selected such that, when inserted into the tube and subjected to mechanical compression in a direction substantially orthogonal to the tube's exterior surface, deforms so that the first and second materials extrude axially at substantially the same rate. In some exemplary embodiments, the sleeve wall thickness may be selected to be thin, or the sleeve may include a multiplicity of axially spaced-apart corrugations formed in at least one exterior or interior surface. The assembly may include stranded composite wires, optionally with a tape covering only a portion of the composite wires.
