Multiple material golf club head
A wood-type golf club head ( 40 ) having a major body ( 50 ), a striking plate insert ( 55 ) and a minor body ( 60 ) is disclosed herein. The major body ( 50 ) is composed of a metal material and has a front wall section ( 72 ), a return section ( 74 ), a sole section ( 76 ), a ribbon section ( 78 ) and a ledge portion ( 80 ). The minor body ( 50 ) is preferably composed of a low density material and has a crown section ( 62 ) and a ribbon section ( 64 ). The striking plate insert ( 55 ) is composed of a metal material. An epoxy-based composition ( 200 ) is placed at a face-sole junction ( 205 ) to lower the amplitude of the sound of the golf club head ( 40 ) during impact with a golf ball.
1. A golf club head comprising:
a body composed of a titanium alloy material;
wherein a moment of inertia about a Izz axis through a center of gravity of the golf club head that ranges from 2800 to 5000 grams-centimeters squared, a moment of inertia about a Ixx axis through the center of gravity of the golf club head that ranges from 2000 to 3500 grams-centimeters squared and a moment of inertia about a Iyy axis through the center of gravity of the golf club head that ranges from 2000 to 3500 grams-centimeters squared;
wherein the golf club head has a length ranging from 3.5 inches to 4.5 inches and a width ranging from 4.0 inches to 5.5 inches;
wherein the golf club head has a volume ranging from 350 cubic centimeters to 495 cubic centimeters;
wherein the golf club head has an amplitude level of less than 118 decibels when impacting a golf ball at a swing speed ranging from 80 MPH to 130 MPH.
2. The golf club head according to claim 1 wherein the golf club head has an amplitude level of approximately 110 decibels when impacting a golf ball at a swing speed ranging from 80 MPH to 130 MPH.
