摘要

A golf club head (20) having products of inertia Ixy, Ixz and Iyz with absolute values below 100 g-cm<2>is disclosed herein. The golf club head (20) has a large volume, a high moment of inertia, or both. Preferably, the moment of inertia, Izz, of the golf club head (20) 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 (20) ranges from 1900 g-cm<2> to 2050 g-cm<2>. Preferably, the golf club head (20) is composed of plies of pre-preg sheets. The volume of the golf club head (20) preferably varies from 300 cm<3> to 600 cm<3>.
