Abstract

A golf club head ( 42 ) having more than 50% of a volume forward of a center of gravity and more than 50% of a mass rearward of the center of gravity is disclosed herein. The golf club head ( 42 ) preferably has a volume ranging from 420 cubic centimeters to 480 cubic centimeters. The golf club head ( 42 ) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 2000 grams-centimeters squared.

Claims (15)

1. A fairway wood-type golf club head comprising:

a body having a face wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall, the heel wall extending 2.0 inches to 5.0 inches rearward from a perimeter of the face wall, the rear wall substantially perpendicular to the heel wall and extending from 2.5 inches to 5.5 inches from an aft edge of the heel wall, and the toe wall substantially perpendicular to the rear wall and the toe wall extending from 2.0 inches to 5.0 inches from an aft edge of the toe wall toward the perimeter of the face wall, wherein the crown, the sole, the face wall, the heel wall, the rear wall and the toe wall define a hollow interior, wherein the heel wall extends rearward from a perimeter of the face wall a distance of least 66% of the length of the heel wall at an angle of 80 degrees to 90 degrees relative to a plane parallel to the farthest extent of the face wall, and the toe wall is substantially parallel to the heel wall;

wherein the golf club head has a volume ranging from 200 cubic centimeters to 600 cubic centimeters and a mass ranging from 135 grams to 200 grams; and

wherein more than 50% of the volume of the golf club head is forward of the center of gravity of the golf club head and less than 50% of the mass of the golf club head is forward of the center of gravity, wherein forward of the center of gravity is toward the face wall.

2. The fairway wood-type golf club head according to claim 1 further comprising a plurality of weight members disposed on at least one of the sole wall, the heel wall, the rear wall, and the toe wall, each of the plurality of weight members having a mass ranging from five grams to thirty grams.

3. The fairway wood-type golf club head according to claim 1 wherein the golf club head has a length, L gch , from a farthest forward edge of the golf club head to a farthest rearward edge of the golf club head that ranges from 3.5 inches to 4.75 inches, and the center of gravity of the golf club head is positioned less than 50% of the length, L gch , from the farthest forward edge.

4. The fairway wood-type golf club head according to claim 3 wherein the center of gravity of the golf club head is positioned from 30% to 49% of the length, L gch , from the farthest forward edge.

5. A wood-type golf club head comprising:

a face component composed of a metal material, the face component having a mass ranging from 80 grams to 120 grams;

an aft-body coupled to the return portion of the face component, the aft-body composed of a non-metal material having a density less than that of the first material, the aft-body having a mass ranging from 30 grams to 60 grams; and

a plurality of weight members disposed on the aft-body, each of the plurality of weight members having a mass ranging from 5 grams to 30 grams;

wherein the golf club head has a volume ranging from 200 cubic centimeters to 600 cubic centimeters;

wherein more than 50% of the volume of the golf club head is forward of the center of gravity of the golf club head and less than 50% of the mass of the golf club head is forward of the center of gravity, wherein forward of the center of gravity is toward the striking plate portion.

6. The wood-type golf club head according to claim 5 wherein the golf club head has a moment of inertia about the Izz axis through the center of gravity of the golf club head which is greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head which is greater than 2000 grams-centimeters squared, and the volume of the golf club head ranges from 420 cubic centimeters to 470 cubic centimeters.

7. The wood-type golf club head according to claim 5 wherein the face component is composed of a titanium alloy material and the aft-body is composed of plies of pre-preg material.
