Abstract

A hockey stick blade comprising a front and a rear blade face, the front blade face comprising at least one front layer of reinforcing fiber material having a first reinforcing fiber density, and the rear blade face comprising at least one rear layer of reinforcing fiber material having a second reinforcing fiber density, the first reinforcing fiber density differing from the second reinforcing fiber density. A hockey stick having such a blade is also disclosed.

Claims (64)

1. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face, the front layer of fiber reinforced material being formed with the fibers thereof disposed in a plurality of front face fiber tows having a first tow width and being spaced apart from each other by a first distance; and

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face, the rear layer of reinforcing fiber material being formed with the fibers thereof disposed in a plurality of rear face fiber tows having a second tow width and being spaced apart from each other by a second distance;

wherein the first tow width differs from the second tow width.

2. The method as defined in claim 1 , wherein:

the front and rear layers of fiber reinforced material are formed with a ratio of the first tow width to the second tow width of approximately 0.2 to approximately 0.8.

3. The method as defined in claim 1 , wherein:

the front and rear layers of fiber reinforced material are formed with a ratio of the first tow width to the second tow width of approximately 0.3 to approximately 0.6.

4. The method as defined in claim 1 , wherein:

the front and rear layers of fiber reinforced material are formed with a ratio of the first tow width to the second tow width of approximately 0.4 to approximately 0.5.

5. The method as defined in claim 1 , wherein:

the plurality of front face fiber tows each contain about a same number of fibers as the plurality of rear face fiber tows.

6. The method as defined in claim 1 , wherein the reinforcing fiber material comprises carbon fibers.

7. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face, the front layer of fiber reinforced material being formed with the fibers thereof disposed in a plurality of front face fiber tows having a first tow width and being spaced apart from each other by a first distance;

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face, the rear layer of reinforcing fiber material being formed with the fibers thereof disposed in a plurality of rear face fiber tows having a second tow width and being spaced apart from each other by a second distance; and

wherein the first distance differs from the second distance.

8. The method as defined in claim 7 , wherein:

the front and rear layers of fiber reinforced material are formed with a ratio of the first distance to the second distance of approximately 0.2 to approximately 0.8.

9. The method as defined in claim 7 , wherein:

the front layer and rear layers of fiber reinforced material are formed with a ratio of the first distance to the second distance of approximately 0.3 to approximately 0.6.

10. The method as defined in claim 7 , wherein:

the front layer and rear layers of fiber reinforced material are formed with a ratio of the first distance to the second distance of approximately 0.5 to approximately 0.6.

11. The method as defined in claim 7 , wherein the plurality of front face fiber tows have a different number of fibers per unit width than the plurality of rear face fiber tows.

12. The method as defined in claim 7 , wherein the plurality of distinct front face fiber tows is greater in number than the plurality of distinct rear face fiber tows.

13. The method as defined in claim 12 , wherein:

each tow of the plurality of distinct front face fiber tows has about the same number of reinforcing fibers as each tow of the plurality of distract rear face fiber tows.

14. The method as defined in claim 7 , wherein the reinforcing fiber material comprises carbon fibers.

15. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face; and

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face, the rear layer forming the rear blade face;

wherein the front and rear layers of fiber reinforced material are formed so that a portion of the front blade face covered by the fibers of the front layer is approximately 1% to approximately 10% greater than a portion of the rear blade face covered by the fibers of the rear layer.

16. The method as defined in claim 15 , wherein the reinforcing fiber material comprises carbon fibers.

17. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face; and

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face, the rear layer forming the rear blade face;

wherein the front and rear layers of fiber reinforced material are formed so that a portion of the front blade face covered by the fibers of the front layer is approximately 1% to approximately 10% smaller than a portion of the rear blade face covered by the fibers of the rear layer.

18. The method as defined in claim 17 , wherein the reinforcing fiber material comprises carbon fibers.

19. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face; and

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face;

wherein an area of the front blade face covered by the fibers of the front layer of fiber reinforced material is a first covered area;

an area of the rear blade face covered by the fibers of the rear layer of fiber reinforced material is a second covered area; and

the front and rear layers of fiber reinforced material are formed with a ratio of the first covered area to the second covered area of approximately 0.7 to approximately 1.2.

20. The method as defined in claim 19 , wherein the reinforcing fiber material comprises carbon fibers.

21. A method of making a hockey stick blade comprising:

applying at least a front layer of fiber reinforced material to a front face of a core of the blade to form a front blade face, the front layer of fiber reinforced material being formed with the fibers thereof defining a first density of fibers and comprising:

a first front group of similarly aligned front face fiber tows having a first tow width and spaced apart from each other by a first distance, and

a second front group of similarly aligned front face fiber tows having a tow width similar to the first tow width and spaced apart from each other by a distance similar to the first distance,

the first front group extending at an angle relative to the second front group;

applying at least a rear layer of fiber reinforced material to a rear face of the core to form a rear blade face, the rear layer of fiber reinforced material being formed with the fibers thereof defining a second density of fibers different from the first density of fibers and comprising:

a first rear group of similarly aligned rear face fiber tows having a second tow width and spaced apart from each other by a second distance, and

a second rear group of similarly aligned rear face fiber tows having a tow width similar to the second row width and spaced apart from each other by a distance similar to the second distance,

the first rear group extending at an angle relative to the second rear group.

22. The method as defined in claim 21 , wherein:

the front face fiber tows of the first front group extend substantially perpendicularly to the front face fiber tows of the second front group; and

the rear face fiber tows of the first rear group extend substantially perpendicularly to the rear face fiber tows of the second rear group.

23. The method as defined in claim 21 , wherein:
