Abstract

A composite material may comprise a composite layer, a metal layer, and an anodized layer. In some cases, the composite layer may comprise a first metal and a fiber material. In some examples, the metal layer may comprise a second metal and be on the composite layer and the anodized layer may be on the metal layer.

First claim

1 . A composite material, comprising:
a composite layer comprising a fiber material and a first metal infiltrating the fiber material; a metal layer on the composite layer, the metal layer comprising a second metal; and an anodized layer on the metal layer.

2 . The composite material of claim 1 , wherein the first metal comprises aluminum, an aluminum alloy, magnesium, a magnesium alloy, titanium, or a titanium alloy.

3 . The composite material of claim 1 , wherein:
the fiber material comprises continuous or discontinuous carbon nanotubes, carbon fibers, glass fibers, ceramic fibers, silicon carbide fibers, aramid fibers, or metal fibers; and the fiber material is in a woven or unidirectional form.

4 . The composite material of claim 1 , wherein the second metal comprises aluminum, aluminum alloy, magnesium, magnesium alloy, titanium, or titanium alloy.

5 . The composite material of claim 1 , wherein the metal layer has a thickness greater than or equal to 50 μm.

6 . The composite material of claim 1 , further comprising:
a second metal layer on a side of the composite layer opposite the first metal layer, the second metal layer comprising a third metal; and a second anodized layer on the second metal layer.

7 . A method, comprising:
obtaining a composite layer comprising a fiber material and a first metal infiltrating the fiber material; applying a second metel the composite layer to form a metal layer; and anodizing the metal layer applied to the composite layer.

8 . The method of claim 7 , comprising:
obtaining the composite layer by bonding aluminum, aluminum alloy, magnesium, magnesium alloy, titanium, or titanium alloy with the fiber material.

9 . The method of claim 7 , wherein:
the fiber material comprises continuous or discontinuous carbon nanotubes, carbon fibers, glass fibers, ceramic fibers, silicon carbide fibers, aramid fibers, or metal fibers; and the fiber material is in a woven or unidirectional form.

10 . The method of claim 7 , comprising:
applying the metal layer by applying a foil to the composite layer and bonding the foil to the composite layer.

11 . The method of claim 7 , further comprising
applying a second metal layer to the composite layer on a side of the composite layer opposite the first metal layer; and anodizing the second metal layer applied to the composite layer.

12 . An electronic device, comprising:
a display; and a housing comprising:
a metal-fiber composite layer comprising a fiber material and a metal matrix;
a metal layer bonded to the metal-fiber composite layer; and
an anodized layer formed on the metal layer.

13 . The electronic device of claim 12 , wherein:
the fiber material comprises continuous or discontinuous carbon nanotubes, carbon fibers, glass fibers, ceramic fibers, silicon carbide fibers, aramid fibers, or metal fibers; and the fiber material is in a woven or unidirectional form.

14 . The electronic device of claim 12 , wherein the metal layer comprises a layer of aluminum, aluminum alloy, magnesium, magnesium alloy, titanium, or titanium alloy.

15 . The electronic device of claim 14 , wherein the metal layer comprises a layer of aluminum or aluminum alloy.
