Ice hockey stick head structure

Abstract

A clubhead structure for ice hockey is characterized by comprising a carbon fiber layer and at least one metal layer. Specifically, a portion of the carbon fiber layer material is replaced with a metal layer in existing clubheads made entirely of carbon fiber. The carbon fiber layer is composed of at least one layer of carbon fiber prepreg. This carbon fiber layer overlaps with the at least one metal layer, and each material layer is covered by a prepreg matrix. After covering, the cross-section of the entire clubhead resembles an annual ring structure. The clubhead is pre-formed and placed in a mold, then cured by heating and pressure. By combining the advantages of carbon fiber and metal, the clubhead achieves a balance of strength, elasticity, vibration control, and durability, thereby improving the power of the swing and the stability and resilience of the precise control of the shot angle, while also improving the feel of the swing.

Claims

1. A hockey stick head structure, characterized in that: the stick head structure includes a carbon fiber layer and at least one metal layer, that is, in an existing stick head made entirely of carbon fiber, a certain percentage of the carbon fiber material is replaced with a metal layer, wherein the carbon fiber layer is composed of at least one layer of carbon fiber prepreg; the carbon fiber layer overlaps with the at least one metal layer, and each material layer is covered by a prepreg matrix, and the overlapping carbon fiber layer and at least one metal layer are punctured in a specific area using a jig as needed to facilitate air release, and after preforming the initial appearance of the stick head, it is cured by heating and pressurizing to form the hockey stick head, and the transverse cross-section of the entire stick head after covering is similar to an annual ring structure.

2. The ice hockey stick head structure as described in claim 1, wherein the thickness of the carbon fiber layer is greater than the thickness of the metal layer and they overlap and cover each other.

3. The head structure of the ice hockey stick as described in claim 2, wherein the metal layer is a thin metal sheet or a metal mesh.

4. The head structure of the ice hockey stick as described in claim 3, wherein the metal layer is a thin metal sheet or a metal mesh, which may be selected from aluminum, aluminum alloy, copper, iron, steel, titanium, titanium alloy, and magnesium-aluminum alloy, and its thickness is less than 200µm (0.0079 inch).

5. The ice hockey stick head structure as described in claim 4, wherein the thickness of each layer of the metal sheet or metal mesh is preferably 6µm (0.0002 inch).

6. A hockey stick head structure, characterized in that: the stick head structure includes a carbon fiber layer and at least one metal layer, that is, a portion of the carbon fiber material in an existing stick head made entirely of carbon fiber is replaced with a metal layer, wherein the carbon fiber layer is composed of at least one layer of carbon fiber prepreg; the carbon fiber layer and the at least one metal layer overlap each other to form a hollow space in the middle, and each material layer is covered by a prepreg matrix, and the overlapping carbon fiber layer and the at least one metal layer are punctured in a specific area as needed to facilitate air release, and after preforming the initial appearance of the stick head, it is cured by heating and pressurizing to form the hockey stick head, and the transverse cross section of the entire stick head after covering is similar to a hollow annual ring structure.

7. The ice hockey stick head structure as described in claim 6, wherein the hollow part of the head structure is further filled with a cushioning material for support, and the transverse cross-section of the entire head is a ring-like structure similar to the one with the cushioning material in the middle.

8. The ice hockey stick head structure as described in claim 7, wherein the hollow portion of the head structure is further filled with a cushioning material for support, wherein the cushioning material may be selected from either foam material or rubber material.

9. The head structure of the ice hockey stick as described in claim 6, wherein the thickness of the carbon fiber layer is greater than the thickness of the metal layer and they overlap and cover each other.

10. The head structure of an ice hockey stick as described in claim 6, wherein the metal layer is a thin sheet of metal or a metal mesh.

11. The head structure of the ice hockey stick as described in claim 10, wherein the metal layer is a thin metal sheet or a metal mesh, which may be selected from aluminum, aluminum alloy, copper, iron, steel, titanium, titanium alloy, and magnesium-aluminum alloy, and its thickness is less than 200µm (0.0079 inch).

12. The head structure of the ice hockey stick as described in claim 11, wherein the thickness of each layer of the metal sheet or metal mesh is preferably 6µm (0.0002 inch).
