Claims17
A wood-type golf club head comprising:
- a body defining a hollow interior, the body having a front opening;
- a face attached over the front opening of the body, the face comprising
- a first layer composed of a metal material, the first layer having a thickness ranging from 0.020 inch to 0.200 inch,
- a second layer attached to an internal surface of the first layer, the second layer composed of a polyurea material, the second layer having a thickness ranging from 0.003 inch to 0.150 inch,
- a third layer attached to an internal surface of the second layer, the third layer composed of a composite material, the third layer having a thickness ranging from 0.005 inch to 0.150 inch, wherein a rear surface of the third layer further defines the hollow interior of the body;
- wherein the face has a total thickness ranging from 0.030 inch to 0.500 inch;
