Abstract
A golf club head with a composite component, such as a crown or a sole, where the composite component has a variable cross-sectional thickness, resulting from imposition of non-uniform pattern of slits cut into one or more charges prior to layup, introduction of resin, and curing is disclosed herein. Methods of making such composite components are also disclosed.
Claims20
A golf club head comprising a component formed from composite materials, the component comprising:
- a plurality of plies of reinforcement fabric;
- and
- a quantity of cured matrix,
- wherein the matrix is bonded to the plurality of plies of reinforcement fabric to form a unitary composite component,
- wherein at least a first ply of reinforcement fabric of the plurality of plies of reinforcement fabric comprises a first plurality of tows,
- wherein the first ply has a first zone in which the first ply has been cut with a plurality of slits such that the first plurality of tows in the first zone are discontinuous,
- wherein the first ply has a second zone in which the first plurality of tows in the second zone are intact and continuous,
- wherein the first zone has a first cross-sectional thickness comprising a thickness of the first ply and a thickness of the cured matrix at the first zone,
- wherein the second zone has a second cross-sectional thickness comprising a thickness of the first ply and a thickness of the cured matrix at the second zone,
- wherein the first cross-sectional thickness is greater than the second cross-sectional thickness, and
- whereby the component has a component cross-sectional thickness that varies across a cross-section of the component.
