Abstract

A golf club shaft that can exhibit similar vibration characteristics to a steel shaft. without losing the characteristics of the carbon shaft in any way The metal fibers are composed in the outer layer of the carbon shaft. and set the direction of the metal fiber to be close to the axis of the rod

Claims (2)

1. A golf club shaft, which has an axial center axis, consists of an inner layer arranged along the circumference of the round called the longitudinal axis, called the inner layer, consisting of a group of stacked reinforcing materials. It is made up of carbon fibers: and the outer layer that is wrapped along the circumference of the so-called inner layer, the so-called outer layer, consists of a thin sheet of resin-impregnated fiberglass cloth. A group of metal fibers is placed on the fiberglass cloth. And protrudes approximately in the direction of the so-called longitudinal axis. And presses a thin sheet of carbon fibers onto the so-called metal fibers. 2. Golf club shafts, as in claim 1, the so-called group of reinforcing materials. Carbon fiber, carbon fiber composite reinforcement material with boron fiber The cladding along the perimeter is called core reinforcing material. And a second reinforcing material, a carbon fiber wrapped along the circumference, is known as a composite power material. 3. The club shaft, as in claim 1, called metallic fibers, has a diameter of 30 to 150 micrometers. Tensile strength 80 to 500 kg force / mm2 and modulus of elasticity 10 to 25 ton force / mm 2 4. Golf club shaft, as in claim 1 called metallic fibers. It is arranged on the so-called fiberglass cloth in a spaced relationship in a size range of 0.2 to 0.8 mm. 5. Golf Club Shafts As in claim 4, the so-called metallic fibers are arranged. On the so-called fiberglass cloth, in spaced ties, the size ranges from 0.2 to 0.3 mm. 6. The golf club shaft, as in claim 1, the so-called metallic fibers are arranged on the so-called. The fiber cloth is at an angle of approximately 3 degrees to approximately 5 degrees relative to the longitudinal axis of the shaft. 7. The golf club shaft, as in claim 1, the so-called metal fibers are arranged on a so-called Fiberglass cloth at an angle of approximately 5 degrees relative to the longitudinal axis of the shaft. 8. Golf club shaft, as in claim No. 2, called material. The shaft reinforcement, consisting of resin-impregnated carbon fibers, is arranged at an angle of approximately 30 degrees to approximately 40 degrees relative to the longitudinal axis of the shaft 9. The club shaft, as in claim 2 called. That the composite reinforcement, consisting of carbon fibers and boron fibers, is arranged at an angle of approximately 3 degrees relative to the longitudinal axis of the shaft, as in claim 2, called. That the second reinforcement, consisting of carbon fibers, is arranged at an angle of approximately 5 degrees relative to the longitudinal axis of the stem. 1.Club shaft, as in claim 1, herein is called resin-impregnated fiberglass fabric, consisting of 40 to 65% fiberglass cloth by weight 1. 2. The shaft of the club, as in claim 1, herein is called a thin sheet of carbon fiber. It consists of carbon fibers arranged at an angle of approximately 3 degrees relative to the longitudinal axis of the stem.
