Abstract

[Item Usage] This creation is about a novel golf club head. [Creation Features] This creation's golf club head has the following features: 1. The club head body is made of stainless steel casting. 2. The entire back of the striking surface is also equipped with fiber reinforced resin (FRP). 3. The concave part of the golf club head is sandblasted to prevent the fiber reinforced resin from peeling off from the metal surface, and a primer treatment is further performed to improve the adhesion of the fiber reinforced resin. 4. A spiral-shaped incremental material of tungsten-nickel alloy is configured. Use specific gravity: 10~12. ;5. 3~4 sheets of long-fiber carbon fiber reinforced resin are laminated to form a shape. The outermost layer uses a mesh-like covering sheet. Carbon fiber with a tensile elastic modulus of 15 tons to 36 tons is used. ;6. In order to prevent a gap from being formed between the long-fiber carbon fiber reinforced resin sheet (prepreg sheet) and the head body, the opening of the golf club head concave portion is narrowed by using a curved surface. ;The golf club head of this invention is shown in the attached figure. Its overall appearance is novel and beautiful. It is the best and most reasonable design based on the use function. It has not been seen in publications or publicly used before the application, and meets the requirements of a new design patent.
