High performance nano-structured metalwood golf club heads and iron heads and components thereof

a golf club head and nano-structure technology, applied in the field of metalwood golf clubs, can solve the problems of low or poor damage response, the strength of neat plastics alone cannot replace the thin-walled titanium and steel crowns common to many designs, and the structural strength, fatigue life and maximum deflection limits of these plastic crowns are not within acceptable performance and durability limits, etc., to achieve the effect of improving the moi and even cor characteristics of the entire head, low density and low cos

Abstract

A metalwood coated at least partially with a nanostructure material offer improved performance over existing golf club heads made from a combination of steel and titanium alloys or composite club heads made in part or wholly from fiber-reinforced plastics (FRPs) and metallic sub-components. The components of the metalwood may be coated with variable thicknesses of electro-deposited nanostructure metals and alloys.

Description

[0001] The present application claims priority to U.S. Ser. No. 60 / 891,471, filed Feb. 23, 2007 and U.S. Ser. No. 60 / 910,781, filed Apr. 9, 2007, the disclosures of which are incorporated herein.BACKGROUND

[0002] The invention generally relates to metalwood golf clubs including drivers, fairway woods, hybrid irons, irons, wedges, putters and utility clubs. More particularly, this invention relates to the design, manufacturing and construction of metalwood golf club heads, hybrid iron heads, iron heads, wedge heads and putter heads and the components that make the heads, using nanostructured materials in a composite design to improve performance and durability. The invention also relates to golf iron heads having face inserts and in particular to the face inserts having nano crystalline materials as one component of a multi-material component system.BRIEF DESCRIPTION

[0003] Due to the competitive nature of many sports, designers and manufacturers often seek ways to improve the performance...
