Definitions

  • Ropes are made from a series of yarns made from natural and synthetic fibers, e.g. made from manila, sisal, hemp, coconut, polyamide, polyester and polyethylene fibers or from metal wires, e.g. steel or copper wires.
  • a strand is called a rope from the number of yarns or wires required for the desired rope diameter.
  • a rope in a hawser or cardeel is made of three or four strands by twisting and a rope in a cable lay is made of three or four cardes. The length of lay is the pitch of the helical yarns or wires in the strand, the strands in the cardel or the cardel in the cable.
  • the invention relates to ropes made of endless inorganic or organic reinforcing fiber profiles impregnated with polymers.
  • Polymers according to the invention are:
  • Inorganic reinforcing fibers are e.g. Glass fibers such as E, ECR, R or S glass fibers or Al2O3 fibers.
  • Organic reinforcing fibers are e.g. Polyaramid fibers, LCP fibers or carbon fibers. Glass, polyaramide and carbon fibers are preferred.
  • Fiber composite profiles impregnated with polymers in which the endless reinforcing fibers lie parallel and are not twisted are known. Such profiles, usually with different cross-sections, can be produced by passing a bundle of endless fibers (rovings) through a bath with a reactive resin or a PUR prepolymer or the melt of a thermoplastic or an LCP and the impregnated bundle through an optionally heated molding nozzle pulls or wrapped it with a thermoplastic thread for shaping, the desired profile, eg a circular or oval cross section, and the resin is cured or cooled.
  • a reactive resin or a PUR prepolymer or the melt of a thermoplastic or an LCP and the impregnated bundle through an optionally heated molding nozzle pulls or wrapped it with a thermoplastic thread for shaping, the desired profile, eg a circular or oval cross section, and the resin is cured or cooled.
  • the polymer has the functions of shaping and maintaining, transmitting thrust to the individual fibers combined in the profile, and protecting the fibers from mechanical, physical, chemical or other corrosive attack.
  • the function of the fibers is to absorb the forces introduced.
  • Such fiber composite profiles have high strengths, they are fully elastic and flexible taking into account the permissible marginal fiber expansion. Depending on the combination of materials used, they are corrosion and weather resistant and flame retardant. When using glass fibers, they are electrical and thermal insulators.
  • ropes can be produced from such polymer-impregnated fiber composite profiles, preferably those with a circular cross-section, if flexible, polymer-impregnated fiber composite profiles with diameters of 0.3 to 12 mm are used and the lay length during stranding adapts to the fully elastic properties of the fiber composite profiles. In general, it is necessary to increase the lay length compared to that of textile yarns or wires.
  • Such ropes are much more flexible than a corresponding individual fiber composite profile with the same overall cross-section, but have the full tensile strength as the starting materials.
  • the ropes can be produced like ropes from textile yarns or metal wires, ie as strands, cardels or cables. They can also be impregnated with a polymer after production. The impregnation with a polymer in particular smoothes the surface of the ropes, so that they become easier to handle or can form a better bond with a further material encasing them.
  • such ropes can also be used coated with another polymer in order to further improve the mechanical properties such as hardness and abrasion resistance, to increase the handling, to color the rope and to further improve the corrosion resistance.
  • Thermoplastics such as PE, PP or PA are used for sheathing.
  • the ropes according to the invention consist mainly of glass, polyaramid or carbon fibers, therefore they have low specific weight, high tensile strength, high elasticity, high modulus of elasticity, a low coefficient of thermal expansion, with glass also low thermal and electrical conductivity and electromagnetic neutrality, they are corrosion-resistant, weather-resistant, wear-resistant and non-flammable.
  • Ropes made from fiber composite profiles of the material combination of unsaturated polyester / glass fiber are characterized by the following parameters and data: Table 1 below shows the number of profiles and their diameter from which a rope is made, the diameter of the rope obtained and the physical properties of the rope.
