    Abstract: The invention provides a metallic foam material with better mechanical properties than known foamed materials, and a method of making such a material. Although known foamed metals are light in weight, and sandwich structures formed of such materials can be formed into structural components, the tendency for the structure to crush and fracture under compressive loading, with consequent crack propagation, limits their use in applications in which the integrity of the component is important. The invention addresses this problem by providing a fibre-reinforced foam that combines the tensile strength of a high strength fibre such as carbon fibres with the impact resistance (through crushing and deformation) of metallic foam. The metal foam imparts a greater strength to the carbon-fibre-reinforced plastics (CFRP) part of the structure than it would have by itself. Under tensile loads, the fibre reinforcement gives the metallic foam enhanced strength and low creep.

    Abstract: In one embodiment, composite constructions of the invention are in the form of a plurality of coated fibers bundled together to produce a fibrous composite construction in the form of a rod. Each fiber has a core formed from a hard phase material, that is surrounded by a shell formed from a binder phase material. In another embodiment of the invention, monolithic sheets of the hard phase material and the binder phase material are stacked and arranged to produce a swirled composite in the form of a rod. In still another embodiment of the invention, sheets formed from coated fibers are arranged to produce a swirled composite. Inserts for use in such drilling applications as roller cone rock bits and percussion hammer bits, and shear cutters for use in such drilling applications as drag bits, that are manufactured using conventional methods from these composite constructions exhibit increased fracture toughness due to the continuous binder phase around the hard phase of the composites. These binder phases increase the overall fracture toughness of the composite by blunting or deflecting the tip of a propagating crack.

    Abstract: Methods of fabricating a metal-matrix composite materials comprise the steps of providing a plurality of fibers, providing a plurality of metal wires, positioning the wires and fibers in alternating fashion on a substrate, covering the wires and fibers with a layer of metal to create a multi-layer composite, and ultrasonically consolidating the composite. Titanium, aluminum and alloys and other metals are applicable to the process. The fibers may be boron, silicon carbide, glass, alumina and other common reinforcements or, alternatively, optical fibers, shape-memory fibers, piezo-ceramic fibers may be used. The fibers or the wires may be of uniform or varying composition, and may b are applied to a working surface separately or simultaneously, in which case they may be collimated and delivered to a working surface in aligned fashion.
