Hockey blade with wrapped, stitched core
View Patent ↗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 stitched along the first layer of preimpregnated tape. A second layer of resin preimpregnated tape wrapped continuously around the first layer of resin preimpregnated tape.
1. A method for forming a construct for a hockey blade comprising:
providing a foam core having a first face and a second face;
adhering a first layer of tape on the first face and the second face of the foam core;
applying a non adhesive scrim on the construct; and
stitching a thread through the foam core wherein the thread creates a pillow effect.
2. The method as in claim 1 further comprising providing a second layer of tape on the first layer of tape.
3. The method as in claim 2 wherein the second layer of tape is thicker than the first layer of tape.
4. The method as in claim 1 wherein the non adhesive scrim is formed from of one of woven fiberglass and polyester and is placed on the first layer of tape.
5. The method as in claim 1 wherein the thread is one of high strength polyester, carbon fiber, and carbon fiber preimpregnated with resin.
6. The method as in claim 1 wherein the thread extends through the foam core to add structural and shear strength and rigidity between the first face and the second face of the core.
7. The method as in claim 1 wherein the construct is stitched along the core in a series of at least three parallel lines of stitching, in a criss-cross pattern or diamond pattern.
8. The method as in claim 2 further comprising bonding the foam core and the layers of tape.
9. The method as in claim 1 wherein the thread is stitched on the first layer of tape and scrim and creates a pillow effect on the first layer of tape when the thread is stitched along the first face of the foam core.
10. A method for forming a construct for a hockey blade comprising:
forming a foam core having a first core face, a second core face, a top core edge, and a bottom core edge;
wrapping a first layer of fiber tape around the first core face, the second core face, the top core edge, and the bottom core edge to form a wrapped foam core comprising a first wrapped core face, a second wrapped core face, a wrapped top core edge, and a wrapped bottom core edge;
placing at least two pieces of non-tacky veil material on the construct;
stitching the construct with a thread, the thread extending between and along the first core face and the second core face through the at least two pieces of non-tacky veil material;
wrapping a second layer of fiber tape around the first layer of fiber tape and the veil material after stitching the construct with the thread;
placing the wrapped foam core in a mold;
heating the mold such that the thread becomes embedded in the foam core;
cooling the mold; and
removing the formed structure from the mold.
11. The method according to claim 10 wherein the formed structure is a hockey blade.
12. The method according to claim 10 wherein the fiber tape is carbon fiber tape preimpregnated with resin.
13. The method according to claim 10 wherein the second layer of tape is substantially thicker than the first layer of tape.
14. The method according to claim 10 wherein a single layer of fiber tape is used in the step of wrapping the first layer of fiber tape around the first core face, the second core face, the top core edge, and the bottom core edge.
15. A method for forming a construct for a hockey blade 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 fiber tape around the first core face, the second core face, the top core edge, and the bottom core edge to form a wrapped foam core comprising a wrapped first core face, a wrapped second core face, a wrapped top core edge, and a wrapped bottom core edge;
placing a first piece of non adhesive scrim on the construct and a second piece of non adhesive scrim on the construct to form a sandwich structure;
stitching the first piece of non adhesive scrim and the second piece of scrim onto the construct with a thread, the thread extending between and along the first core face and the second core face;
adhering a second layer of fiber tape to the wrapped first core face and the wrapped second core face to form a preform after stitching the first piece of non adhesive scrim and the second piece of scrim onto the construct;
placing the preform in a mold;
heating the mold;
cooling the mold; and
removing the formed structure from the mold.
16. The method according to claim 15 wherein the formed structure is a hockey blade.
17. The method according to claim 15 wherein the fiber tape is carbon fiber tape preimpregnated with resin.
18. The method according to claim 15 wherein the second layer of tape is substantially thicker than the first layer of fiber tape.
19. The method according to claim 15 wherein a single layer of fiber tape is used in the step of wrapping fiber tape around the first core face, the second core face, the top core edge, and the bottom core edge.
