[0002] Wire rope is a metal product with high strength and high toughness, which is widely used in the crane hoisting industry. In recent years, with the development of science and technology, large-tonnage hoisting operations have become increasingly frequent, and the requirements for wire rope performance are also increasing. High breaking and lightweight wire ropes are gradually attracting attention. Carbon fiber is a new type of high-strength material with a carbon content of more than 95%. It is lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is suitable for application in the field of wire ropes. Carbon fiber composite materials have been widely used in various fields.

[0003] With the continuous development of science and technology and people's pursuit of quality of life, steel wire ropes are widely used in many fields, such as lifting, traction, and hoisting. However, existing steel wire ropes often have problems of insufficient durability during use, and are prone to wear, corrosion, and breakage, which affect their service life and safety. At present, in the field of steel wire ropes, in order to increase its breaking tension, it is necessary to increase the metal area, which will cause the weight of the steel wire rope to increase. Therefore, it is necessary to increase the breaking tension of the steel wire rope without increasing the weight of the steel wire rope.
