Abstract
A multiple-material golf club and a method for forming said golf club is disclosed herein. The multiple-material golf club preferably is a driver that has a metal face cup and a thin-walled, compression molded, composite aft body with precise IML and OML geometry. The molding composite used to form the compression molded aft body preferably comprises a plurality of randomly oriented, pre-spread carbon fiber bundles and a thermoset or thermoplastic matrix material.
Claims16
A golf club head comprising at least one part,
- wherein the at least one part comprises a first molding compound,
- wherein the first molding compound comprises a matrix material, a plurality of carbon fibers having a length of less than 0.25 inch, and at least one of a plurality of carbon nanotubes and a plurality of carbon graphene platelets,
- wherein the carbon fibers are randomly oriented within the matrix material, and
- wherein the golf club head has a coefficient of restitution of 0.81 to 0.84.
A golf club head comprising at least one part,
- wherein the at least one part comprises a laminate composite material and a molding compound,
- wherein the molding compound comprises a matrix material, a plurality of carbon fibers having a length of at least 0.25 inch and no more than 2 inches, and at least one of a plurality of carbon nanotubes and a plurality of carbon graphene platelets,
- wherein the carbon fibers are randomly oriented within the matrix material,
- wherein the matrix material is selected from the group consisting of a vinyl ester and an epoxy, and
- wherein the laminate composite material and the molding compound are co-molded to form the part.
