A composite knife made from layers of Metal Matrix Composite (MMC) is disclosed. It includes a middle layer of fibrous preform including a hard insert placed longitudinally at its periphery. The hard insert, after sharpening, represents the cutting blade portion of the composite knife. The composite knife further includes a carrier which forms the load bearing member of the cutting blade, as well as forming the integral handle of the composite knife. The carrier portion of the composite knife includes at least one top and at least one bottom layers of fibrous preform, sandwiching the middle layer that contains the cutting edge portion of the knife. A metallic material is infiltrated within the fibrous preforms and extends throughout the composite blade structure forming the MMC knife, the metallic material bonding the middle layer within the carrier, and bonding the top and bottom surface of the hard insert within the carrier.

Method of manufacturing a metal matrix composite component includes the steps of providing a first tubular member having a first end and an opposite second end, the first tubular member's first end being formed as a first end block; positioning a metal matrix composite tubular member concentrically the first tubular member; positioning a second tubular member concentrically over metal matrix composite tubular member, second tubular member having a first end and an opposite second end, the second tubular member's second end being formed as a second end block; welding first tubular member's first end to the second tubular member's first end, and the first tubular member's second end to second tubular member's second end, to join the first and second tubular member and thereby to form a metal matrix composite preform; and consolidating metal matrix composite preform by a hot isostatic pressing process to form the metal matrix composite component.

A method of producing a composite material of aluminum and a carbon material includes applying a coating liquid containing carbon fibers, a binder, and a solvent for the binder in a mixed state on an aluminum foil to form a coating layer on the aluminum foil, removing the solvent contained in the coating layer to obtain a coated foil in which a carbon fiber layer is formed on the aluminum foil, a roll formation step of winding the coated foil in a roll shape to obtain a roll, removing the binder contained in the carbon fiber layer of the roll, and extruding the roll after the binder removal step. In the coating step, the coating liquid is applied on the aluminum foil so that a coating amount of the carbon fibers contained in the coating layer becomes equal to or less than 40 g/m.sup.2.

A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

The present disclosure discloses a continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite and a preparation method thereof, composing of a carbon fiber with a volume fraction of 30-55%, an inorganic powder with a volume fraction of 3-25% and a matrix with a volume fraction of 20-67%, wherein the inorganic powder is wrapped on the surface of the carbon fiber filament or embedded in the carbon fiber bundle, and the concentration gradually decreases from the fiber filament to the surface of the fiber bundle. The preparation method of the composite is as follows: (1) pretreating the carbon fibers; (2) preparing a slurry of the inorganic powder; (3) widening the pretreated carbon fiber to form a carbon fiber strip, and then carrying out electrophoretic deposition on the inorganic powders; (4) preparing a preform from the deposited carbon fibers; and (5) compounding a matrix in the preform.
