Abstract

A composite material for a component of a golf club head is disclosed herein. The composite material includes a composite layers and at least one an interlaminar layer that includes one of vertically aligned carbon nanotubes, Z-Axis aligned carbon fibers or graphene platelets. In one preferred embodiment, the golf club head component is a face component.

Claims (80)

wherein an Area_Ply k is the area of each composite ply (k) in the laminate,

wherein an Area Additive (k) is the area of the reinforcement present between offsetting plies (k and k+1),

wherein the additive laminate ratio of the composite material ranges between 0.05 and 0.9.

2 . The composite material according to claim 1 wherein each of the first composite layer and the second composite layer has a fabric area weight ranging from 20 gsm to 500 gsm.

3 . The composite material according to claim 1 wherein each the first composite layer and the second composite layer comprises at least one of a carbon fiber, fiberglass fiber, or aramid fiber.

4 . A composite material for a component of a golf club head, the composite material comprising:

a first composite layer;

a second composite layer; and

an interlaminar layer comprising one of vertically aligned carbon nanotubes, Z-Axis aligned carbon fibers or graphene platelets;

wherein the first composite layer and the second composite layer comprise a plurality of plies, each of the plurality of plies a unidirectional orientation, a bi-axial orientation or a tri-axial orientation;
