AI Technical Summary
Existing composite material designs for golf club heads suffer from insufficient bonding strength, which can easily lead to gaps and noise, affecting the feel and durability of the shot. Furthermore, the manufacturing process is complex and costly, making it difficult to fully utilize the material's performance advantages.
The golf club head is made of composite material with an internal rough surface structure. By setting a honeycomb or wavy rough surface on the internal surface of the club head body and co-curing it with composite units, the pouring temperature and pressure are optimized to ensure uniform filling and tight bonding of the material.
It improves the bonding strength of composite materials, enhances the feel and distance of the ball, extends mold life, reduces production costs, is suitable for various material combinations, and enhances the durability and consistency of products.
