Abstract
A golf club head is disclosed having a club face comprised of a plurality of plates that act in concert to provide a spring-like response when the club impacts a golf ball. The plates are fluidly coupled by providing appropriate surfaces to the plates at their interface or by locating a viscous fluid between the plates. The plates are held in place by coupling them to the head body. One or more plates may be integrally formed with the body of the golf club head. Various parameters may be selected to optimize response or to customize the response for different golfing styles including the relative thickness of the plates, the presence of a viscous fluid between the plates, the type and viscosity of the viscous fluid, the material of the plates, (and hence, their coefficient of elasticity) and the type of mechanical coupling of the plates to the body of the golf club head.
