Abstract

A composite material includes a plurality of fibers embedded in a metal matrix. The composite material further includes a plurality of particles disposed in the metal matrix. At least 25% of the fibers contact or are spaced less than 0.2 micrometers from an adjacent fiber within the metal matrix.

First claim

The invention claimed is:

1. A composite material comprising:
a plurality of fibers embedded in a metal matrix; and
a plurality of particles disposed in the metal matrix;
wherein at least 25% of the fibers contact or are spaced less than 0.2 micrometers from an adjacent fiber within the metal matrix.

2. The composite material of claim 1 , wherein at least 50% of the fibers contact or are spaced less than 0.2 micrometers from an adjacent fiber within the metal matrix.

3. The composite material of claim 1 , wherein the composite material is in the form of a wire.

4. The composite material of claim 3 , wherein the fibers comprise substantially continuous fibers.

5. The composite material of claim 1 , wherein the plurality of particles are present at less than 1 wt. % based upon the total dry weight of the fibers.

6. The composite material of claim 1 , wherein the plurality of particles are present at less than 0.1 wt. % based upon the total dry weight of the fibers.

7. The composite material of claim 5 , wherein the plurality of particles have a mean diameter of no greater than 300 nanometers.

8. The composite material of any one of claim 5 , wherein the composite material does not comprise any or all of whiskers, short fibers, or chopped fibers.

9. A composite wire comprising:
a plurality of substantially continuous fibers embedded in a metal matrix, the plurality of substantially continuous fibers and metal matrix forming a substantially continuous composite wire; and
a plurality of particles disposed in the metal matrix;
wherein the plurality of particles are present at less than 0.1 wt. % based upon the total dry fiber weight of the substantially continuous fibers; and
wherein the plurality of particles have a mean diameter of no greater than 100 nanometers.

10. A cable comprising at least one composite wire of claim 9 .

11. A stranded cable comprising at least one composite wire of 9 , wherein the stranded cable comprises:
a core wire defining a center longitudinal axis;
a first plurality of wires stranded around the core wire; and
a second plurality of wires stranded around the first plurality of wires.

12. A helically stranded cable including at least one composite wire of claim 9 , wherein the helically stranded cable is comprised of:
a core wire defining a center longitudinal axis;
a first plurality of wires helically stranded around the core wire in a first lay direction at a first lay angle defined relative to the center longitudinal axis and having a first lay length; and
a second plurality of wires helically stranded around the first plurality of wires in a second lay direction at a second lay angle defined relative to the center longitudinal axis and having a second lay length.

13. The stranded cable of claim 12 , wherein the core wire comprises at least one composite material of claim 9 .

14. The stranded cable of any one of claim 12 , wherein each of the first plurality of wires comprises at least one composite wire of claim 9 .

15. The stranded cable of claim 14 , wherein each of the second plurality of wires comprises at least one composite wire of claim 9 .

16. The stranded cable of claim 15 , wherein each wire has a cross-section in a direction substantially normal to the center longitudinal axis, and wherein the cross-sectional shape of each wire is selected from the group including circular, elliptical, and trapezoidal.

17. The stranded cable of claim 16 , wherein the cross-sectional shape of each wire is circular, and wherein the diameter of each wire is from 1 mm to 2.5 cm.

18. The stranded cable of claim 17 , wherein each of the first plurality of wires and the second plurality of wires has a lay factor of from 10 to 150.

19. The stranded cable of 18 , wherein the first lay direction is the same as the second lay direction.

20. The stranded cable of claim 19 , wherein a relative difference between the first lay angle and the second lay angle is greater than 0° and no greater than 4°.
