Abstract
The present of invention provides a golf club shaft structure, characterized in that: the shaft structure comprises overlapping carbon fiber layers and at least one layer of plastic film, and/or a metal sheet with a thickness of less than 0.2 mm (200 micrometers; 0.0079 inches), each layer of material being covered by a matrix and formed by thermosetting. This combination of different materials in the shaft endows it with excellent elasticity, toughness, and shock absorption performance, thereby achieving better power transmission and control. This allows the golf club to provide easily controllable accuracy during long-distance swings or short-distance putting, and provides shock absorption and a unique feel for long-distance swings.
Claims17
A golf club shaft structure comprising a carbon fiber layer and at least one layer plastic film, the carbon fiber layer having at least one layer of carbon fiber prepreg, and overlapping and completely covering with the at least one layer plastic film each other, and the carbon fiber layer and each of the plastic film with a matrix in contact each other, after covering, the cross-section of the golf club shaft resembling the annual of a tree, and forming the golf club shaft by heating and curing.
A golf club shaft structure comprising a carbon fiber layer and at least one layer metal sheet, the carbon fiber layer having at least one layer of carbon fiber prepreg, and overlapping and completely covering with the at least one layer metal sheet having a thickness of less than 0.2 mm (200 μm;
- 0.0079 inch) each other, and the carbon fiber layer and each of the metal sheet with a matrix in contact each other, after covering, the cross-section of the golf club shaft resembling the annual of a tree, and forming the golf club shaft by heating and curing.
A golf club shaft structure comprising a carbon fiber layer and at least one layer metal mesh, the carbon fiber layer having at least one layer of carbon fiber prepreg, and overlapping with the at least one layer metal mesh each other, and the carbon fiber layer and each of the metal mesh with a matrix which is made of thermoplastic (TP) in contact each other, and forming the golf club shaft by heating and curing.
