KFRP strength member for optic cable
Product Features:
Light weight and high strength: KFRP has the characteristics of low density and high strength. Its ratio of strength and modulus are higher than those of steel wire and GFRP;
Low expansion: KFRP has a lower coefficient of thermal expansion than steel wire and GFRP in a wide range of temperature;
Impact and break resistance: KFRP has much higher tensile strength (≥1600Mpa).
Even it is broken, the remained tensile strength could be 1300Mpa;
Good flexibility: KFRP is flexible and easy to be bent. Its minimum bending diameter is 24 times of the diameter of KFRP rod;
Good aesthetic and flexible, especially for the indoor layout.
