Abstract: Methods for non-destructive testing of synthetic ropes is described, where the rope in use is subjected to X-ray, terahertz, permanent magnetic field or electromagnetic analysis to determine a pattern, the results of the analysis are compared with a standard pattern determined by the analysis, and the results of the comparison are used in determining whether the rope is fit for use; where the rope comprises at least two types of fibers, the first fiber type has a density which differs from the density of the second fiber type and the second fiber type is of the same polymer material as the first fiber type, but provided with a high-density or low-density material. Ropes suitable for use in this method are also described.

Abstract: 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).
