Lifecycle Performance of Escape Systems
Lifecycle Performance of Escape Systems. This study investigates the effect of cycle / flex fatigue on aramid fiber core ropes versus other fiber configuration. Although the strength of 100% aramid fiber ropes is impressive, the strength rapidly decreases after cyclic rappels. These studies, for consistency, only examine the effects of the fatigue due to decent devices, although the bending through pulleys, corners, and edges also greatly influence the reduction of strength.
