  • Patent number: 4050230
    Abstract: The rope of this invention comprises a plurality of strands each having a twisted reinforcing fiber bundle, thermosetting resin applied to the fiber bundle, and a thermoplastic resin cover enclosing the fiber bundle. Each strand in the rope is kept to substantially a round sectional shape by the twisted fiber bundle.The method for forming the rope comprises the steps of twisting the reinforcing fibers in such a manner that the tensile strength of the twisted fibers is not reduced to less than 50% of the fibers not twisted, applying an uncured thermosetting resin to the twisted fibers, covering the fibers with a molten thermoplastic resin, cooling the thermoplastic resin to cover the fibers with solidified thermoplastic resin and thereby forming a strand, forming a rope structure from a plurality of the strands, and heating the rope structure to cure the thermosetting resin applied on the fibers.
