Mixed material golf club head
First Claim
1. A golf club head comprising:
- a metallic front body including a strike face and a surrounding frame that extends rearward from a perimeter of the strike face;
a rear body coupled to the metallic front body to define a substantially hollow structure, the rear body including a crown member and a sole member coupled to the crown member, the sole member comprising;
a structural layer formed from a filled thermoplastic material and bonded to the crown member, the structural layer including a plurality of apertures extending through a thickness of the structural layer; and
a resilient layer bonded to an external surface of the structural layer such that the resilient layer extends across each of the plurality of apertures, wherein the resilient layer is formed from a fiber-reinforced thermoplastic composite material;
wherein the structural layer and the resilient layer each comprise a common thermoplastic resin component, and wherein the structural layer is directly bonded to the resilient layer without an intermediate adhesive.

Abstract
A golf club head includes a metallic front body coupled with a rear body to define a substantially hollow structure. The metallic front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. The rear body includes a crown member and a sole member coupled to the crown member. The sole member comprises a structural layer formed from a filled thermoplastic material and a fiber reinforced composite resilient layer bonded to an external surface of the structural layer. The structural layer includes a plurality of apertures extending through a thickness of the structural layer, and the resilient layer extends across each of the plurality of apertures. The structural layer and the resilient layer each include a common thermoplastic resin component, and are directly bonded to each other without an intermediate adhesive.
