The invention relates to a composite twisted cable formed by impregnating carbon fibers with thermoplastic resin, and provides a fiber composite twisted cable which allows downsizing of a reel by being easy to be bent, can be transported to mountain areas which is normally hard to achieve a transport with a large vehicle, is hard to be curled, and is superior in workability. It is a cable having 1×n structure which is formed by impregnating bundles of carbon fibers with thermosetting resin, then twisting a plurality of strands each formed by covering an outer periphery of the bundle with a fiber, and then curing the thermosetting resin by applying the heat treatment, and a core strand and side strands which constitute the cable are separated and independent without being bonded so as to allow independent behavior of the respective strands when the cable is bent.
A fiber composite twisted cable having 1×n structure which is formed by impregnating bundles of carbon fibers with thermosetting resin, then twisting a plurality of strands each formed by covering an outer periphery of the bundle with a fiber, and then curing the thermosetting resin by heat treatment, wherein an unstuck process is applied, wherein said unstuck process is a process to forcedly separate the respective strands of the twisted cable having the thermosetting resin cured and forcedly release a bonded state of the strands, such that each of a core strand and side strands surrounding the same, which constitute 1×n structure, is allowed to perform independent behaviors when the cable is bent in a direction orthogonal to its longitudinal direction.
