Abstract

A construct for a hockey blade that includes a foam core. The foam core includes a first core face, a second core face, and a core edge. A first layer of resin preimpregnated tape is wrapped continuously around the first core face, the core edge and the second core face. A thread is placed along the first layer of preimpregnated tape. A second layer of resin preimpregnated tape wrapped continuously around the first layer of resin preimpregnated tape.

First claim

I claim:

1. A method comprising:
forming a foam core, the core comprising a first core face, a second core face, a top core edge and a bottom core edge;
wrapping the foam core with a first layer of fiber tape, the first layer of fiber tape extending continuously along the first core face, top core edge, second core face and bottom core edge of the foam core, wherein the wrapped core has a first wrapped face, a second wrapped face, a top wrapped edge and a bottom wrapped edge;
supplying the wrapped foam core with a thread, the thread extending along one of the first wrapped face and the second wrapped face;
wrapping a portion of the wrapped core with a second layer of fiber tape;
placing the preform in a mold;
heating the mold;
cooling the mold; and
removing the formed structure from the mold.

2. The method according to claim 1 wherein the formed structure is a hockey blade.

3. The method according to claim 2 wherein the fiber tape is carbon fiber tape preimpregnated with resin.

4. The method according to claim 3 wherein the second layer of tape is substantially thicker than the first layer.

5. The method according to claim 4 wherein a single layer of fiber tape is used in the step of wrapping the foam core with a first layer of fiber tape.

6. The method according to claim 4 wherein a plurality of layers of tape are used in the step of wrapping the preform with a second layer of fiber tape.

7. The method according to claim 6 wherein the thread is polyester.

8. The method according to claim 7 further comprising the step of, after wrapping the foam core with a first layer of fiber tape, placing a non-tacky veil on the first wrapped face and the second wrapped face of the wrapped core.

9. The method according to claim 6 wherein the thread is carbon fiber.

10. The method according to claim 8 wherein the thread follows a predetermined criss-cross pattern.

11. A method comprising:
forming a foam core;
wrapping the foam core with a first layer of fiber tape;
supplying the wrapped foam core with a thread, the thread extending along a first wrapped face or a second wrapped face;
wrapping a portion of the wrapped core with a second layer of fiber tape to form a preform;
placing the preform in a mold;
heating the mold;
cooling the mold; and
removing the formed structure from the mold.

12. The method according to claim 11 wherein the formed structure is a hockey blade.

13. The method according to claim 11 wherein the fiber tape is carbon fiber tape preimpregnated with resin.

14. The method according to claim 13 wherein the second layer of tape is substantially thicker than the first layer.

15. The method according to claim 14 wherein a single layer of fiber tape is used in the step of wrapping the foam core with a first layer of fiber tape.

16. The method according to claim 11 further comprising the step of, after wrapping the foam core with a first layer of fiber tape, placing a non-tacky veil on the first wrapped face and the second wrapped face of the wrapped core.

17. A method comprising:
forming a foam core;
wrapping the foam core continuously with a first layer of fiber tape;
placing a non-tacky veil on a portion of the wrapped core;
supplying the wrapped foam core with a thread, the thread extending along a first wrapped face or a second wrapped face of the wrapped core;
wrapping a portion of the wrapped core with a second layer of fiber tape;
placing the preform in a mold;
heating the mold;
cooling the mold; and
removing the formed structure from the mold.

18. The method according to claim 17 wherein the formed structure is a hockey blade.

19. The method according to claim 17 wherein the fiber tape is carbon fiber tape preimpregnated with resin.

20. The method according to claim 17 wherein the second layer of tape is substantially thicker than the first layer.

21. The method according to claim 20 wherein a single layer of fiber tape is used in the step of wrapping the foam core with a first layer of fiber tape.
