Abstract

In example implementations, an enclosure is provided. The enclosure includes a first layer of carbon fiber and a second layer of a carbon fiber pattern fabricated from a plastic. The first layer of carbon fiber is formed in a shape of a portable electronic device. An antenna window is formed in the first layer of the carbon fiber. The second layer of the carbon fiber pattern has a same shape and a same size as the first layer of carbon fiber.

Claims (35)

1. An enclosure, comprising:

a first layer of carbon fiber that is formed in a shape of a portable electronic device;

an antenna window formed in the first layer of the carbon fiber, wherein the antenna window is laser cut into the first layer of carbon fiber; and

a second layer of a carbon fiber pattern fabricated from a plastic, wherein the second layer has a same shape and a same size as the first layer of carbon fiber, and wherein the second layer is positioned to cover the first layer including the antenna window.

2. The enclosure of claim 1 , wherein the first layer of carbon fiber comprises a unidirectional carbon fiber composite or a multi-directional weaved carbon fiber composite.

3. The enclosure of claim 1 , wherein the antenna window is injection molded into an opening of the first layer of the carbon fiber.

4. The enclosure of claim 1 , wherein the antenna window comprises a glass or a clear plastic.

5. The enclosure of claim 1 , wherein the antenna window is located over a location of a wireless antenna of the portable electronic device.

6. The enclosure of claim 5 , wherein a shape and a size of the antenna window is based on a shape and a size of the wireless antenna.

7. The enclosure of claim 1 , wherein the second layer is adhered to the first layer of carbon fiber via out-mold decoration process.

8. An apparatus, comprising:

a wireless antenna;

a processor communicatively coupled to the wireless antenna; and

an enclosure to enclose the wireless antenna and the processor, wherein the enclosure comprises:

a first layer of carbon fiber;

an antenna window formed in the first layer of the carbon fiber, wherein the antenna window is laser cut into the first layer of carbon fiber; and

a second layer of a carbon fiber pattern fabricated from a plastic, wherein the second layer has a same shape and a same size as the first layer, and wherein the second layer is positioned to cover the first layer including the antenna window.

9. The apparatus of claim 8 , wherein the antenna window is injection molded into an opening of the first layer of the carbon fiber.

10. The apparatus of claim 8 , wherein the antenna window comprises polycarbonate.

11. The apparatus of claim 8 , wherein the antenna window is located over a location of the wireless antenna of the portable electronic device.

12. The apparatus of claim 8 , enclosure further comprises:

an adhesive layer between the first layer and the second layer, wherein the adhesive layer is cured via an out-mold decoration process.

13. A method, comprising:

cutting a carbon fiber material into a shape of a portable electronic device;

cutting an opening in the carbon fiber material in a location where a wireless antenna of the portable electronic device is located, wherein the cutting the opening is performed via a laser cutting operation;

injection molding an antenna window into the opening;

applying an adhesive layer over the carbon fiber material and the antenna window;

applying a carbon fiber pattern onto the adhesive layer, so that the carbon fiber pattern covers the carbon fiber material and the antenna window; and

adhering the carbon fiber pattern onto the carbon fiber material via an out-mold decoration process that cures the adhesive layer.

14. The method of claim 13 , wherein the injection molding is performed with a glass fiber or a plastic.

15. The apparatus of claim 8 , wherein the antenna window comprises at least one of a rectangular shape, a “T” shape, or an “L” shape.

16. The enclosure of claim 1 , further comprising:

an adhesive layer applied between the first layer of carbon fiber and the second layer.

17. The enclosure of claim 16 , wherein the adhesive layer is cured to couple the second layer onto the first layer of carbon fiber.

18. The enclosure of claim 1 , wherein the adhesive layer is formed as part of the first layer of carbon fiber.
