POLYETHYLENE ROPE WITH HIGH STRENGTH-STRENGTH RATIO |
摘要 |
A rope including polyethylene elongate elements oriented in the length direction of the rope, where for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope. The polyethylene elongate elements including tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %. The distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. Such a rope shows a high strength-strength ratio (the ratio between the strength under use conditions and the fresh strength of the rope). |

1. A rope comprising:
polyethylene elongate elements oriented in the length direction of the rope wherein for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope, the polyethylene elongate elements comprising tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %, and the distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. |
