Abstract: An adjustable golf club putter head is disclosed herein. The putter head includes a removable top plate that can be swapped with a different top plate with a different material composition and alignment pattern to affect the cosmetics of the putter head and also adjust the putter head's mass properties.
Abstract: A golf ball with improved durability is disclosed herein. The golf ball has a mantle layer comprising a blend of ionomers and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 5 to 15 weight percent of the mantle layer.
Abstract: A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners. The support member may be part of a lattice structure formed via binder jetting.

Abstract: A method for forming a golf ball core with a nanofiller masterbatch is disclosed herein. The method includes mixing the nanofiller masterbatch, a graphene masterbatch material with other materials to form a core mixture, wherein the masterbatch preferably comprises 1-80% by weight of nanofillers and 20-99% by weight of a carrier polymer.
Abstract: A golf ball comprising layers that have from 0.05% to 70% by weight of a radio-opaque filler, and wherein the concentration of the radio-opaque filler is measurably different in each layer is disclosed herein. The radio-opaque filler is preferably a compound based on barium, bismuth, tungsten, iodine, or reduced iron.
Abstract: A golf ball core, mantle, and/or cover layer(s) of golf ball having a composition comprising functionalized aluminosilicate particles having a particle size of less than 50 ?m is disclosed herein. The aluminosilicate microspheres with an average diameter less than 50 ?m are functionalized with, but not limited to, polysulfide, vinyl, amino, epoxy, hydroxyl, carboxyl, methacryloyl, hydrocarbon, mercapto and isocyanate.
Abstract: Methods of manufacturing a golf club head with one or more stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. One method includes the steps of preparing a wax mold of a golf club head including a plate stiffening member with excess material, casting the golf club head, and machining away the excess material. Another method includes the steps of casting a golf club body, providing a plate stiffening member, providing a face component such as a face cup, tack welding the plate stiffening member and the face component to the golf club body, and welding these parts together.

Abstract: A method of manufacturing a golf club head with a plurality of stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. The method includes the steps of preparing a wax of a golf club head body having at least one through-hole, a hollow interior, and at least one receiving pocket, preparing waxes of one or more stiffening members, inserting the wax of the stiffening members into the through-hole and seating its opposite end in the receiving pocket, bonding each of the stiffening members to the body with an adhesive material to form a combined wax mold, and casting a golf club head from the combined wax mold.

Abstract: A golf ball comprising layers that have from 0.05% to 70% by weight of a radio-opaque filler, and wherein the concentration of the radio-opaque filler is measurably different in each layer is disclosed herein. The radio-opaque filler is preferably a compound based on barium, bismuth, tungsten, iodine, or reduced iron.
Abstract: A golf ball with a cover layer composed of a blend of non- or partially neutralized copolymeric or terpolymeric ionomer(s), hydroxyl-functionalized styrenic block copolymer and silane coupling agent (SCA). The amount of SCA is preferably between 0.01 and 2.0 weight percent based on the total weight of the polymer composition. The cover layer preferably has a Shore A hardness less than 90.
Abstract: A golf club head with plate-like, heel and toe side internal stiffeners is disclosed herein. Each stiffener has a planar portion extending approximately parallel with a portion of the striking face, and is entirely disposed within an interior cavity of the golf club head. The heel side stiffener is connected to top, sole, and heel walls of the club head, with a toe-side edge unconnected to any other portion of the head, and the toe side stiffener is connected to the top, sole, and toe walls of the club head, with a heel-side edge unconnected to any other portion of the head. The toe and heel side edges may have large concavities that distribute mass away from the geometric face center and toward the heel and toe sides of the golf club head.
Abstract: A golf ball with improved durability is disclosed herein. The golf ball has a mantle layer comprising a blend of ionomers and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 5 to 15 weight percent of the mantle layer.
Abstract: A method of optimizing golf club head and golf ball design is disclosed herein. The method includes inputting a RBF for stress, a RBF for CT and a RBF for ball speed into an Adaptive Simulated Annealing algorithm to generate an optimized structure for the club head for ball speed.
