Cycle history data and elongation characteristics for polyester and aramid wire-lay construction ropes

High performance ropes have unique properties that are derived from their fiber and construction. Wire-lay construction rope manufactured from 1W81 polyester with SeaGuard(R) finish and Kevlar(R) 29 aramid are observed in this study while experiencing 250,000+ cycles of tension-tension fatigue. The results indicate general behavioral trends. The numerical data obtained can be used in computer models to evaluate the appropriate use of the tested ropes based on their engineering properties.
