Abstract
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.
