Patent Images
1. A golf club head comprising:
- a body having a crown, a sole, a front wall with an opening, and a ribbon with an exterior recess opposite the opening, the body composed of a plies of pre-preg material;
a striking plate insert positioned within the opening, the striking plate insert composed of a metal material and having a mass ranging from 40 grams to 80 grams; and
a weighting member positioned within the recess of the ribbon, the weighting member having a mass ranging from 15 grams to 60 grams and composed of a metal material;
wherein the golf club head has a center of gravity located less than 1.27 inches from an exterior surface of the striking plate, and a moment of inertia about the Iyy axis through the center of gravity of the golf club head greater than 2500 grams-centimeters squared.

Abstract
A golf club head (20) having a center of gravity located relatively forward toward the front wall (30) or striking plate (40) of the golf club head (20), and a relatively high moment of inertia about the Iyy axis through the center of gravity of the golf club head (20) is disclosed. The golf club head (20) preferably has a volume between 300 cubic centimeters and 500 cubic centimeters. The golf club head (20) preferably has a mass between 105 grams and 300 grams. The positioning of the of the center of gravity of the golf club head (20) and the relatively high moment of inertia Iyy through the center of gravity provide for a golf club with greater robustness and better performance.
