Golf clubs, ski poles, and fishing gear are all early applications of carbon fiber tubes. The important difference in weight between carbon fiber golf clubs and steel clubs directly means the difference in swing speed for most players. That is, the carbon fiber rod is 2-4 mph faster, which means that the hitting distance will increase by 6-12 yards. The fishing rod made of carbon fiber has the characteristics of lightness, firmness and high tensile strength. The carbon fiber content used in the production of fishing rods directly determines the value and grade of the fishing rod. The general carbon content is about 30%-90%, but Special care should be taken when using carbon fiber fishing rods.
