Golf club head with a stress-reducing structure
A golf club head with a face component with a stiffening member is disclosed herein. The golf club having products of inertia Ixy and Ixz with absolute values below 100 g-cm 2 and a positive product of inertia Iyz is disclosed herein. The golf club has a large volume, a high moment of inertia, or both. Preferably, the moment of inertia, Izz, of the golf club head about a vertical axis Z through the center of gravity ranges from 3000 g-cm 2 to 5000 g-cm 2 , and a moment of inertia, Iyy, about a horizontal axis Y through the center of gravity of the golf club head is greater than 1900 g-cm 2 .
1 . A golf club head comprising:
a face component with a stiffening member;
a central body component comprising
a crown portion composed of a first carbon based material,
a sole portion composed of a second carbon based material,
wherein the crown portion is attached to the sole portion,
wherein the component has a front opening and a rear opening with a hollow interior;
an aft-component;
wherein the face component is attached to a front opening of the central body and the aft component is attached to a rear opening of the central body;
wherein the golf club head has an absolute value of an Iyz product of inertia less than 125 g-cm 2 ;
wherein the golf club head has an Izz moment of inertia ranging from 4500 g-cm 2 to 6000 g-cm 2 ;
wherein the first carbon based material has continuous fibers and the second carbon based material has chopped fibers.
2 . The golf club head according to claim 1 wherein the golf club head has an Iyy moment of inertia ranging from 2500 g-cm 2 to 4000 g-cm 2 .
