Benefits of technology

[0009] The present invention is directed generally to composite materials and process for making the same. The composite materials of the present invention exhibit desirable properties including high strength and low weight, and are simpler and more cost efficient to fabricate than composite materials possessing similar properties. The processes of the present invention have been found to afford considerable flexibility in tailoring the properties of the resulting composite materials to meet the performance requirements of a range of applications, such as rocket parts, exhaust systems, aerospace structures, machine tools, armor plates, and protective coatings. The composite materials of the present invention can be in the form of, for example, particle-strengthened materials, fiber-strengthened materials, network-strengthened materials, and bi- / tri-continuous-strengthened materials.

Problems solved by technology

The fabrication process requires a relatively short period of time to complete.

example 1

Particle-Strengthened Composite No. 1

[0060] A 50:50 (wt. %) mixture of fullerenes and diamond powder (0.5 μm) was prepared by ball milling. A green body was shaped in a die under 0.5 GPa at room temperature. It was placed into the reaction cell of the high pressure-high temperature (HPHT) chamber and sintered at a pressure of about 3 GPa, at a temperature of about 800° C. and for a holding time of about 1,000 seconds.

example 2

Particle-Strengthened Composite No. 2

[0061] A 50:50 (wt. %) mixture of fullerenes and diamond powder (50 μm) was prepared by ball milling. A green body was shaped in a die under 1 MPa at room temperature. It was placed into the reaction cell of the high pressure-high temperature (HPHT) chamber and sintered at a pressure of about 3 GPa, at a temperature of about 800° C. and for a holding time of about 1,000 seconds.

example 3

Particle-Strengthened Composite No. 3

[0062] A 70:30 (wt. %) mixture of diamond (50 μm) and diamond (0.5 μm) / fullerene powder was prepared by ball milling. A green body was shaped in a die under 0.1 GPa at room temperature. It was placed into the reaction cell of the high pressure-high temperature (HPHT) chamber and sintered at a pressure of about 1 GPa, at a temperature of about 700° C. and for a holding time of about 1,000 seconds.

Abstract

A composite material composed of a matrix phase bonded by a carbon binder phase derived from sintered carbon nanoparticles such as, for example, fullerenes. The present invention further relates to a method of making such composite materials which includes the steps of dispersing a sufficient amount of carbon nanoparticles into a matrix phase, and compressing the carbon nanoparticles-containing matrix phase at a sufficient pressure and temperature over a sufficient time to facilitate the conversion of the carbon nanoparticles into a nanostructured carbon binder phase, thereby yielding the composite material.
