Abstract
Official abstract text for this publication.
Composite materials include a non-ferrous metal matrix with reinforcing carbon fiber integrated into the matrix. The composite materials have substantially lower density than non-ferrous metal, and are expected to have appreciable strength. Methods for forming composite non-ferrous metal composites includes combining a reinforcing carbon fiber component, such as a woven polymer, with non-ferrous metal nanoparticles and sintering the non-ferrous metal nanoparticles in order to form a non-ferrous metal matrix with reinforcing carbon fiber integrated therein.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite material comprising: a continuous non-ferrous metal matrix of sintered non-ferrous metal nanoparticles sintered at a temperature of less than 450° C.; and at least one reinforcing carbon fiber, a portion of which is contactingly surrounded by the non-ferrous metal matrix, wherein at least 50% of a surface area of the at least one reinforcing carbon fiber contacts the non-ferrous metal matrix. 2. The composite material as recited in claim 1 , wherein the at least one reinforcing carbon fiber is fully encapsulated within the non-ferrous metal matrix. 3. The composite material as recited in claim 1 , wherein the at least one reinforcing carbon fiber comprises a plurality of spatially separated layers of reinforcing carbon fiber. 4. The composite material as recited in claim 1 , having density less than 7 g/cm 3 . 5. The composite material as recited in claim 1 , having density less than 6 g/cm 3 . 6. The composite material as recited in claim 1 , having density less than 5 g/cm 3 . 7. The composite material as recited in claim 1 , wherein the continuous non-ferrous metal matrix comprises an alloy of at least one non-ferrous metal selected from the group consisting of: titanium, tungsten, copper, zinc, nickel, tin, aluminum, and germanium. 8. A composite material comprising: at least one reinforcing carbon fiber; and a continuous metal matrix, of sintered metal nanoparticles sintered at a temperature less than 450° C., having an average dimension less than 20 nm and formed of a metal selected from a group consisting of titanium and tungsten, contactingly surrounding at least a portion of the at least one reinforcing carbon fiber, wherein at least 50% of a surface area of the at least one reinforcing carbon fiber contacts the non-ferrous metal matrix. 9. The composite material as recited in claim 8 , having density less than 7 g/cm 3 . 10. The composite material as recited in claim 8 , having density less than 6 g/cm 3 . 11. The composite material as recited in claim 8 , having density less than 5 g/cm 3 .
