Abstract
A rope structure comprising a plurality of rope subcomponents, a plurality of bundles combined to form the rope subcomponents, a plurality of first yarns and a plurality of second yarns combined to form the bundles. In one embodiment, the first yarns have a tenacity of approximately 25-45 gpd and the second yarns have a tenacity of approximately 6-22 gpd. In another embodiment, the first yarns have a breaking elongation of approximately 2%-5% and the second yarns have a breaking elongation of approximately 2%-12%.
Claims11
A rope structure comprising:
- a plurality of rope subcomponents, where the rope subcomponents are combined to form the rope structure;
- a plurality of bundles, where the bundles are combined to form the rope subcomponents;
- a plurality of first yarns, where the first yarns
- are formed of at least one material selected from the group of materials comprising HMPE, LCP, Aramids, and PBO, and
- have a tenacity of approximately 25-45 gpd;
- and
- a plurality of second yarns, where the second yarns
- are formed of at least one material selected from the group of materials comprising polyolefin, polyethylene, polypropylene, and blends or copolymers of the two, and
- have a tenacity of approximately 6-22 gpd;
- wherein
- the first and second yarns are combined to form the bundles.
A method of forming a rope structure comprising the steps of:
- providing a plurality of first yarns, where the first yarns
- are formed of at least one material selected from the group of materials comprising HMPE, LCP, Aramids, and PBO, and
- have a tenacity of approximately 25-45 gpd;
- providing a plurality of second yarns, where the second yarns
- are formed of at least one material selected from the group of materials comprising polyolefin, polyethylene, polypropylene, and blends or copolymers of the two, and
- have a tenacity of approximately 6-22 gpd;
- combining the plurality of first yarns and the plurality of second yarns to form a plurality of bundles;
- combining the plurality of bundles to form a plurality of rope subcomponents;
- and
- combining the plurality of rope subcomponents to form the rope structure.
