Abstract
The invention relates to a carbon fiber composite core for a cable and a manufacturing method thereof. The carbon fiber composite core comprises a carbon fiber beam which consists of carbon fiber yarns stretching along the same length direction, or the carrier of the composition of a carbon fiber and an epoxy resin series; a reinforcing fiber which is wound outside the carrier, or the reinforcement for the composition of the reinforcing fiber and the epoxy resin series; and other reinforcing fibers other than the carbon fiber, or the protector of the composition of the reinforcing fiber and the epoxy resin series, which is covered outside the reinforcement. The method comprises the following steps of: soaking the carbon fiber yarns in glue and pressing to form the carbon fiber beam; soaking the reinforcing fiber in the glue and winding outside the carbon fiber beam; and soaking the other reinforcing fibers other than the carbon fiber in the glue and covering on the outermost part. The radial shearing force of the composite core is effectively improved by adding the reinforcement; the winding of the reinforcement does not influence the integral concentricity of the composite core; and the other reinforcing fibers other than the carbon fiber are taken as the protector, so that the corrosion to an aluminum conductor when the protector contacts the aluminum conductor is avoided.
