Abstract:
The invention relates to a high strength fibers comprising a coating of cross-linked silicone polymer, and ropes made thereof. The fibers are preferably high performance polyethylene (HPPE) fibers. The coating comprising a cross-linked silicone polymer is made from a coating composition comprising a cross-linkable silicone polymer. The rope shows markedly improved service life performance in bending applications such as cyclic bend-over-sheave applications. The invention also relates to the use of a cross-linked silicone polymer in a rope for an improvement of bend fatigue resistance.

Abstract:
Non-metallic rigging chain (6) is formed with a plurality of linked flexible loops (7). Each loop (7) has a core (22) which consists of a continuous strand (24) of non-metallic materially coiled upon itself. The coiled core material is sheathed within a woven outer fabric (26). Except for the two material loops of each chain, one loop (7) is formed by coiling a continuous strand (24) of core material in linked relation within a pair of completed loops (7). The length of each chain is determined by the diameter of its loops and the number of loops linked together. One end of the strand (24) is fixed to a pin (50) on a link of a metal chain (34) driven around two spaced sprockets (30,32) interlinked with the pair of completed loops (7). Each metal link of the driven chain (34) has a pin (50) to define the position of the strand (24) as it is unwound from a supply spool (52).
