Spearfishing Kit Stainless Steel Fishing Stringer 6FT Carbon Fiber Roller Pole Spear 8FT Hand Spear Hawaiian Sling 9FT Fishing Harpoon Hunting Polespear With Slip Tip Advantages of Carbon Fiber  Carbon fiber composite materials have higher fatigue strength, with the fatigue strength of steel and aluminum being 30-50% of the tensile strength, while carbon fiber composite materials can reach 70-80% The significant characteristics of carbon fiber are light weight, good fiber size, and high tensile strength, as well as the combination of temperature resistance, wear resistance, and low expansion coefficient. 1. Carbon fiber materials have high strength. The tensile strength of carbon fiber materials is above 3500MPa. 2. The modulus of carbon fiber materials is high. The elastic modulus of carbon fiber materials can reach over 230GPa. 3. Carbon fiber materials have low density and high specific strength. The weight of carbon fiber is 1/4 that of steel and 1/2 that of aluminum alloy. Carbon
