Woven and packed composite constructions

A composite construction comprising:

• a structure of two or more material phases that are woven together;
• wherein the material phases are in the form of a substantially continuous band formed from materials selected from the group consisting of:
• polycrystalline diamond, polycrystalline cubic boron nitride;
• carbides, borides, nitrides, carbonitrides from groups IVA, VA, and VIA of the Periodic Table;
• cermets, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta;
• and mixtures thereof.

A composite construction comprising:

• an ordered structure of two or more material phases;
• wherein a first material phase is in the form of a substantially continuous band comprising polycrystalline diamond;
• and
• wherein the second material phase is in the form of a substantially continuous band formed from a material selected from the group consisting of cermets, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof, the first and second material phases being interwoven with one another to provide a repeating arrangement of first and second material phases.

A composite construction comprising:

• an ordered structure of two or more material phases arranged together in a packed configuration;
• wherein the material phases can be formed from the same or different materials selected from the group consisting of:
• polycrystalline diamond, polycrystalline cubic boron nitride;
• carbides, borides, nitrides, and carbonitrides from groups IVA, VA, and VIA of the Periodic Table;
• and mixtures thereof;
• cermets, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof;
• and
• wherein the ordered structure is positioned along a working surface of the composite construction.

A method for making a composite construction having an ordered structure comprising the steps of:

• forming a multi-layer laminate film comprising one or more different materials;
• cutting one or more slices from the multi-layer laminate film;
• combining the one or more slices with one or more slices taken from another multi-layer film to form a multi-layer construction with multiple layers of materials forming the films positioned along a construction surface;
• sintering the multi-layer construction to form the composite construction having an ordered structure of the multiple layers of materials positioned along a working surface.

A roller cone drill bit comprising:

• a body having a number of legs that extend therefrom;
• cutting cones rotatably disposed on an end of each leg;
• a plurality of cutting inserts disposed in the cutting cones, therein at least a portion of the cutting inserts are formed from a composite construction having a structure of two or more material phases that are woven together;
• wherein the material phases include materials selected from the group consisting of polycrystalline diamond, polycrystalline cubic boron nitride;
• carbides, borides, nitrides, and carbonitrides from groups IVA, VA, and VIA of the Periodic Table, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof.

A drag drill bit comprising:

• a body having a head and having a number of blades extending away from a head surface, the blades being adapted to engage a subterranean formation during drilling;
• a plurality of shear cutters disposed in the blades to contact the subterranean formation during drilling, each shear cutter comprising a substrate and a layer of cutting material disposed thereof, the cutting material comprising a composite construction having a structure of two or more material phases that are woven together;
• wherein the material phases include materials selected from the group consisting of polycrystalline diamond, polycrystalline cubic boron nitride;
• carbides, borides, nitrides, and carbonitrides from groups IVA, VA, and VIA of the Periodic Table, Co, Ni, Fe, W, Mo, Cu, Al, Nb, Ti, Ta, and mixtures thereof.
