Problems solved by technology

Because the mandrel is a round rod, and the surface of the round rod is smooth and complete, the central hole of the carbon fiber golf club shaft is a round hole, and the thickness of the shaft is uniform and consistent. The bending resistance and torsion resistance are poor, and the hitting effect is also poor, which really needs further improvement

Embodiment Construction

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0022] see figure 1 and figure 2 As shown, in the carbon fiber golf club shaft disclosed in the present invention, the central hole is a square hole 10, such as a rectangular hole or a square hole.

[0023] The molding method of the carbon fiber golf club shaft of the present invention is as follows: image 3 and Figure 4 shown:

[0024] First select a square mandrel 1, such as a rectangular mandrel (see image 3 ) or square mandrel; release agent and resin;

[0025] Next, the carbon fiber material 4 is wrapped on the mandrel 1 to form a round rod on the outside; specifically, the carbon fiber material 4 can be laid on each side of the square mandrel 1 layer by layer, and the carbon fiber material 4 is formed from the inside. It gradually becomes smaller layer by layer, so that the carbon fiber material 4 wraps the core rod 1 an...

Abstract

The invention discloses a carbon fiber brassie body, a center hole of which is provided with a square hole. The invention also discloses a forming method of the carbon fiber brassie body, which comprises the steps of: firstly, selecting a square core rod, and applying a release agent and resin; secondly, coating a carbon fiber material on the core rod until the surface is shaped as a round rod; thirdly, winding a BOPP ((Biaxially Oriented Polypropylene Laminated Polyethylene) film on the carbon fiber material, and placing in a die cavity of a die; fourthly, heating at a temperature of 130 DEG C for curing carbon fiber; and finally, removing the die, drawing the core rod out, removing the BOPP film, grinding the surface, checking a blank, and varnishing to prepare the carbon fiber brassie body. The thickness of the brassie body is gradually increased on each side of the square hole, so that the brassie body plays a role of reinforcing rib to ensure that the bending resistance and the torque resistance of the brassie body can be enhanced, thus the batting effect is improved.

Description

technical field [0001] The present invention relates to the technical field of golf clubs, in particular to a carbon fiber golf club shaft and a molding method thereof. Background technique [0002] A golf club consists of a shaft, a head and a grip. In the prior art, the shaft is usually made of carbon fiber. The carbon fiber material is wrapped on the mandrel, and then put into the cavity of the mold, and the carbon fiber is cured by heating, and then the mandrel is removed after demoulding, and the carbon fiber golf club shaft is made. Because the core rod is a round rod, and the surface of the round rod is smooth and complete, the center hole of the carbon fiber golf club shaft is a round hole, and the thickness of the shaft is uniform and consistent. The bending resistance and torsion resistance are poor, and the hitting effect is also poor, and it really needs further improvement. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide...
