Embodiment Construction

[0026] The present invention is described with reference to the enclosed detailed embodiment, wherein the same numbers are used. In particular, the present invention is directed to improved metal wood clubs which incorporate a composite, reinforced build up of an anisotropic fiber material such as graphite.

[0027] Referring to FIG. 1, the present invention comprises a hybrid golf club face 10 comprising an anisotropic material such as fiber and graphite 12 affixed as an insert in the resin. The fibers and graphite are affixed to the inside club face 16.

[0028] The graphite crystal is one of the most anisotropic (meaning exhibiting properties with different values when measured along axes in different directions) bodies known. Anisotropy is the direct result of the layered structure with extremely strong carbon-carbon bonds in the basal plane. Properties of graphite crystals illustrating this anisotropy are shown in Table 1. Of particular interest for the electronics cooling market i...

Abstract

A hybrid golf club face comprising: a surface having a metallic outer surface with an anisotropic composite material affixed to the inside of a metal wood head section in such an orientation to provide a restated hitting characteristic.

Description

FIELD OF THE INVENTION [0001] The present invention is directed to the field of golf clubs. In particular, the present invention discloses a metal wood golf club utilizing composite anisotropic materials bonded or co-molded to an interior surface of a golf club striking head in order to achieve or alter a preset coefficient of restitution (COR). BACKGROUND OF THE INVENTION [0002] The Coefficient of Restitution, or “COR,” relates to the energy transfer that occurs when one object collides with another. In terms of golf clubs, COR is directly related to the speed of a golf ball as it rebounds from a clubface. Generally, a club with higher COR will generate greater ball velocity, equaling more distance. [0003] COR is expressed as a percentage. To measure a club's COR, balls are fired at a clubface at a fixed speed, known as initial speed. The speed at which the balls rebound is known as rebound speed. The COR is generally equal to the rebound speed divided by the initial speed. For exa...
