Abstract
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
Claims15
A hybrid rope comprising a core element containing high modulus fibers surrounded by at least one outer layer containing metallic members,
- wherein the core element is coated with a polymer comprising a copolyester elastomer containing soft blocks in the range of 10 to 70 wt %.
A method of manufacturing a hybrid rope, the method comprises the steps:
- (a) providing a core element, wherein the core element includes high modulus fibers;
- (b) coating the core element with a polymer comprising copolyester elastomer containing soft blocks in a range of 10 to 70 wt %;
- and
- (c) twisting a plurality of metallic members together around the core element to form a metallic outer layer.
