SEM images after cut resistance tests

The dataset consists of raw scanning electron microscopy images of nylon 6 fibers taken from climbing ropes after undergoing cut resistance tests. The cut resistance of climbing ropes remains an unsolved problem despite numerous attempts in the last 20 years. In recent years, new laboratory test methods have been developed (Edelrid, Elmenzwick, and UIAA 101). This dataset presents fiber failure modes they induce and compares them with those after a simulated accident. The fiber fractography revealed four main failure modes. These failure modes included lateral pressure with high-stress concentration, lateral pressure with low-stress concentration, high-speed tensile break, and molten and fused fiber ends. In very isolated cases, ductile breaks were found. None of the test methods could comprehensively imitate the overall rope-breaking mechanism. They mimic failure modes in either the sheath or the core. Edelrid's test mimics the failure modes of a simulated accident rather in the sheath but not in the core. On the contrary, the Elmenzwick method mimics the failure modes rather in the core but not in the sheath. The dynamic test method from the International Climbing and Mountaineering Association (UIAA 101) best mimics failure modes in the core but not in the sheath.
