Abstract:
1. A golf club head comprising: a face having a ball striking surface and an inner surface opposite the ball striking surface, the face having an area of highest response located proximate a center of the ball striking surface, wherein the face is formed of a first material and further comprises an insert forming at least a portion of the area of highest response, the insert being formed of a second material having a thermal modulus response that is different from a thermal modulus response of the first material, wherein the thermal modulus response of the second material is configured such that heat generated by an impact of a golf ball striking surface of at least 90 ft/s is sufficient to reduce a modulus of the second material by at least 10% relative to the modulus of the second material at ambient conditions; and a body connected to the face and extending rearward from the face.
