Abstract

An injection molded composite component includes a groove extending from a first surface of the composite component and a tubing material placed within the groove and formed integrally with the composite component such that the tubing material forms an integrated conduit on the first surface of the composite component.

First claim

What is claimed is:

1. A composite component, comprising:
a first surface; and
a conduit integrated with the first surface and having a first end extending from the conduit at a first position of the composite component and a second end extending from the conduit at a second position of the composite component;
wherein the conduit protrudes from the first surface of the composite component, the first surface comprises a resin layered on a preform, and the conduit comprises a tubing material bonded to the preform with the resin such that the resin is formed around the tubing material.

2. The composite component of claim 1 , wherein one of a rubber tube, a plastic tube, a metal tube, a bare wire, and a shielded wire is molded into the first surface of the composite component.

3. The composite component of claim 1 , wherein the preform includes a first preform and a second preform and the tubing material is encircled by the second preform such that the tubing material is between the first and second preforms.

4. The composite component of claim 1 , wherein the first surface includes a groove protruding from the first surface, and the groove is configured to receive one of a tube and a wire.

5. The composite component of claim 1 , wherein the composite component is a vehicle liftgate and the conduit is configured to transfer windshield wiper fluid.

6. A method for manufacturing a composite component with an integrated conduit, comprising:
providing a first mold for the composite component;
placing a preform on the first mold;
placing a tubing material on the preform;
placing a second mold for the composite component on an assembly comprising the first mold, the preform, and the tubing material such that the preform and tubing material are between the first and second molds; and
performing an over molding process by injecting a resin between the first and second molds such that the tubing material is encapsulated by the resin and formed integrally with the composite component, wherein the tubing material is enclosed by a foam material, and both the tubing material and the foam material are encapsulated by the resin during the over molding process.

7. The method of claim 6 , wherein the first mold includes a groove configured to receive the tubing material.

8. The method of claim 6 , wherein the preform includes a first preform and a second preform, and the method includes placing the tubing material on the first preform and placing the second preform on top of the tubing material.

9. The method of claim 6 further comprising pressurizing the tubing material when injecting the resin to prevent compression of the tubing material during the over molding process.

10. The method of claim 6 , wherein the second mold includes a groove configured to receive the tubing material.

11. The method of claim 6 , wherein the tubing material is one of a rubber tube, a plastic tube, a metal tube, a bare wire, and a shielded wire.

12. An injection molded composite component, comprising:
a groove extending from a first surface of the composite component; and
a tubing material placed within the groove and formed integrally with the composite component such that the tubing material forms an integrated conduit on the first surface of the composite component, wherein the tubing material is enclosed within a foam material, and the tubing material and the foam material are over molded with the first surface.

13. The composite component of claim 12 , wherein the tubing material comprises one of a rubber tube, a plastic tube, a metal tube, a bare wire, and a shielded wire is molded into the first surface of the composite component.

14. The composite component of claim 12 , wherein the tubing material is pressurized.
