Abstract
A golf club head includes a front body and a rear body coupled to the front body to define a hollow cavity therebetween. The front body includes a strike face that defines a ball striking surface, a hosel, and a frame that at least partially surrounds the strikeface and extends rearward from a perimeter of the strikeface away from the ball striking surface. The strike face and frame are formed from a thermoplastic composite comprising a thermoplastic polymer having a plurality of discontinuous fibers embedded therein. Each of the plurality of discontinuous fibers have a length of less than about 40 mm. The specific gravity of the thermoplastic can range between 1.0 and 2.0. In some embodiments, the thermoplastic composite is 20% to 70% fibers by volume.
