METHOD FOR NON-DESTRUCTIVE RESEARCH OF SYNTHETIC CABLES AND SUITABLE FOR USING A CABLE IN IT

摘要

1. A non-destructive method for researching synthetic cables, in which the cable is exposed to X-ray, terahertz radiation, a constant magnetic field or electromagnetic field to determine an image during use, the analysis results are compared with a standard image determined by the analysis, and the comparison results are used to determine whether the cable is suitable for use, wherein the cable contains fibers of at least two types, where the fiber of the first type has a flat NOSTA which is different from a second density type of fiber, and wherein fibers of the second type consists of the same polymeric material as the fiber of the first type, but having a high or low density material plotnosti.2. A method according to claim 1, wherein the high density material or low density material is attached to the first type of fiber using glue or during the coating process. The method of claim 1 or 2, wherein the high density material contains metal and / or its derivative or alloy, preferably copper, nickel, cerium, rubidium, zinc, iron, zirconium, tantalum, barium, silver, gold, platinum, titanium or iridium, preferably zinc. 4. The method according to claim 1 or 2, in which the standard image and the image of the cable during use are obtained from a repeating periodic change of the image associated with the structure of the cable, and in which the comparison between the two images is a measure of the change of the periodic periodic change of image associated with the structure of the cable caused by the use of a cable. 5. The method of claim 1 or 2, wherein the first type of fiber is present in
