Hockey blade with pin-reinforced core

1. A hockey stick blade apparatus, comprising:

a molded preform structure, further comprising:

a foam core comprising a first core face, a second core face, a top core edge, and a bottom core edge;

a first plurality of discrete pins injected substantially parallel to one another into a first area of the first core face with a first spacing density and extending between the first core face and the second core face within the foam core;

a second plurality of discrete pins injected substantially parallel to one another into a second area of the first core face with a second spacing density higher than the first spacing density and extending between the first core face and the second core face within the foam core; and

a layer of fiber tape extending along the first core face, the top core edge, the second core face, and the bottom core edge of the foam core,

wherein each of the first plurality and the second plurality of discrete pins has two opposing pointed ends,

wherein a portion of each of the first plurality and the second plurality of discrete pins extends out of the form core beyond the first core face and the second core face, and

wherein the portion is configured to embed into the layer of fiber tape.

2. The hockey stick blade apparatus of claim 1 , wherein the layer of fiber tape is preimpregnated with resin prior to molding of the molded preform structure.

3. The hockey stick blade apparatus of claim 1 , wherein the first plurality and the second plurality of discrete pins are regularly spaced apart.

4. The hockey stick blade apparatus of claim 1 , wherein the first plurality and second plurality of discrete pins extend through the layer of fiber tape.

5. The hockey stick blade apparatus of claim 1 , wherein the first plurality and second plurality of discrete pins comprise fiber pins.

6. The hockey stick blade apparatus of claim 1 , wherein a selected pin, from the first plurality and the second plurality of discrete pins, is injected at an angle relative to a surface normal of the first core face at a point of injection of a first fiber pin.

7. A hockey blade structure formed by a method comprising the steps of:

forming a foam core, the foam core comprising a first core face, a second core face, a top core edge, and a bottom core edge;

injecting a first plurality of discrete pins substantially parallel to one another at a first angle into a first area the first core face, the first plurality of discrete pins extending between the first core face and the second core face;

injecting a second plurality of discrete pins substantially parallel to one another at a second angle into a second area of the first core face, the second plurality of discrete pins extending between the first core face and the second core face;

wrapping the foam core with a layer of fiber tape to form a wrapped core, the layer of fiber tape extending along the first core face, the top core edge, the second core face, and the 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; and

molding the wrapped foam core in a mold,

wherein the first plurality of discrete pins has a first spacing density, and the second plurality of discrete pins has a second spacing density higher than the first spacing density,

wherein each of the first plurality and the second plurality of discrete pins has two opposing pointed ends,

wherein a portion of each of the first plurality and the second plurality of discrete pins extends out of the form core beyond the first core face and the second core face, and

wherein the portion is configured to embed into the layer of fiber tape.

8. The hockey blade structure of claim 7 , wherein the first angle is relative to a first surface normal of the first core face at a point of injection of a selected first pin, from the first plurality of discrete pins, and the second angle is relative to a second surface normal of the first core face at a point of injection of a selected second pin, from the second plurality of discrete pins.

9. The hockey blade structure of claim 8 , wherein the first angle and the second angle are approximately zero degrees.

10. The hockey blade structure of claim 8 , wherein the first angle and the second angle are between approximately 15 and 75 degrees.

11. The hockey blade structure of claim 7 , wherein the first plurality and second plurality of discrete pins are regularly spaced apart from one another on the first core face.

12. The hockey blade structure of claim 7 , wherein the first plurality and second plurality of discrete pins comprise fiber pins.

13. The hockey blade structure of claim 7 , wherein the first plurality and the second plurality of discrete pins are regularly spaced apart from one another on the first core face.
