Description

Carbon ceramic golf club head

The present invention relates to a golf club, in particular to a golf club head made of carbon-ceramic composite materials.

Conventional golf clubs can be roughly divided into three parts, namely club head, shaft and grip. Among them, the club head can be composed of a club head shell and a striking panel. The club head shell is usually made of metal (stainless steel, titanium Alloy, etc.) or carbon fiber toughened resin matrix composite material (FRP); the striking panel needs to have high hardness and resistance to beating, usually using metal (such as titanium alloy), ceramic or FRP.

The conventional FRP used in golf club heads is generally made of carbon fiber cloth or other polymer fiber cloth, first coated with epoxy resin or phenolic resin and other colloids, stacked layer by layer, and then hot pressed to harden the colloid to form. However, The hardness of metal is small, and it is easy to form dents after long-term high-speed impact. FRP is also the same; ceramics have high hardness, and the striking sound is crisp, but it is easy to break and cannot be hit.

In the prior art, the Republic of China Patent Application No. 80215884 "Improved Structure of Golf Club Head (2)" discloses a golf club The head includes a body, a composite material layer, and a percussion panel. The body is made of metal. The composite material layer is epoxy-coated carbon fiber. The percussion panel is made of composite materials or titanium or ceramic materials. The document is improved The material of the striking panel is more durable than the metal club head. However, the composite materials, titanium metal, and ceramic materials are as mentioned above. If they are used in the striking panel, the hardness of metal and composite materials is small, and it is easy to form dents after long-term high-speed impact. Ceramics have high hardness but are fragile, so they are not resistant to beating. There is room for improvement.

In the prior art, the ROC Patent Application No. 81212668 "Improved Structure of Golf Wood Head" discloses a golf club head that includes a shell, a substrate, and a fiber-reinforced resin layer. The shell is integrally formed by metal casting The fiber-reinforced resin layer is made of carbon fiber coated with epoxy resin, and a striking panel can be provided. The striking panel is made of composite material or titanium metal or ceramic material. This document simplifies the engineering by integrally forming the shell and the substrate. The fiber-reinforced resin layer is combined with the beating panel to adjust and improve the ball-head striking surface. However, composite materials, titanium metal, and ceramic materials are as mentioned above. For the beating panel, the hardness of metal and composite materials is smaller and longer. It is easy to form depressions after high-speed impact over time. The ceramic has high hardness but is easy to break, so it is not resistant to beating. The fiber-reinforced resin layer and the beating panel are made separately, and the preparation procedure is relatively complicated.

Therefore, there is a great need in the industry for a material that has the advantages of ceramics, has a crisp sound, and is hard to produce dents, but at the same time has a material that is resistant to hitting and is not easy to break, so that it can be used as the striking panel of the golf head.
