Abstract
A new structure for a golf club head which is lighter yet with lower impact loss and featuring internal reinforcements is designed according to research results from impact mechanics. The impact capability of the golf club head can be improved by placing the reinforcement structures close to the striking face and its adjacent support. The design of the golf club head keeps the same weight as the current standard stainless steel head while lowering kinetic energy loss during the impact or reduces the weight of the club head while maintaining the same energy loss. This golf club head is formed by a combined 'superplastic forming and diffusion bonding' method for fabricating a titanium alloy golf club head. The basic procedures are: using three titanium sheets; machining shallow cavities into one of the sheets, which later provide the reinforcing function; applying stop-off to the area where diffusion bonding is not desired; sealing the three sheets by welding along their peripheries together with two gas supply tubes, placing the assembly into the die and attaching the gas supply; after vacuuming and heating up, the assembled part is subjected to subsequent diffusion bonding and superplastic inflation processes which yield a titanium golf club head with an internally strengthened striking face.
