Abstract
A contoured golf club face provides increased structural integrity for a given weight and size is described and shown along with a method for its design. The contoured golf club face includes a vertical stiffening region, a tapered horizontal stiffening region, four similar contoured quadrants of increasingly thinning material toward the center of each quadrant, and thickening regions at face/sole and face/crown intersection regions. The thicknesses of adjoining regions are gradually blended to provide a smooth contoured surface. The present golf club face is light weight, is structurally resistant to impact deformation, is resistant to initial and long-term failure, has its mass center located at its sweet spot, exhibits inertial axes which are aligned with vertical and horizontal axes (i.e. primary club force directions: ball impact force and club centrifugal force directions), and produces acoustical tones. A club incorporating the present contoured golf club face may be provide a certain first acoustical sound when used to hit a ball with a certain first specific area of the face (e.g. the sweet spot or sweet spot region) and to provide a different second acoustical sound when …
