Abstract
A multiple-material golf club head with an improved scarf joint between the crown and the body is disclosed herein. The golf club preferably is a driver that has a metal body comprising a striking face, a sole, a return portion, a front flange, and a rear flange, and a composite crown having a scarf joint region, a transitional thickness region directly behind the scarf joint region, and a constant thickness region directly behind the transitional thickness region. The thickness distribution along the crown, in combination with the tapered edge of the scarf joint and its intersection with the front flange, greatly reduces the stress placed on critical portions of the club head and improves overall golf club head durability.
