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, and between a center of the strike face and the hosel, greater than about 50% of the plurality of discontinuous fibers are aligned within about 30 degrees of parallel to a horizontal axis extending from the center of the strike face to the hosel.
