Abstract

The invention discloses a carbon fiber wire. The carbon fiber wire comprises a three-layer structure which sequentially comprises an inner layer, a soft aluminum or aluminum alloy cladding layer and a soft aluminum type stranded wire layer from inside to outside, and the inner layer comprises four carbon fiber layers. The carbon fiber wire has the advantages that tensile stress is pre-stored in the cladding process by adopting a continuous aluminum cladding technology, and seamless cladding is conducted on carbon fiber core rods through an aluminum cladding technology, so that the carbon fiber wire does not directly make contact with air, and then influences of oxidization, ultraviolet irradiation, water vapor, salt and alkali and the like on the carbon fiber core rods are eliminated; transformation is conducted on a traditional steel-cored aluminum strand hardware fitting, and therefore the carbon fiber wire can achieve pressure welding through a common hardware fitting; the tensile strength of the carbon fiber wire reaches 2,600 MPa, and the maximum allowable operation temperature ranges from 180 DEG C to 200 DEG C; the cost of the carbon fiber wire can be reduced by 30% to 50% compared with a common carbon fiber wire; the resin-glass conversion temperature of the carbon fiber wire is significantly lowered compared with the common carbon fiber wire, and low sag is kept.
