Abrasion Resistance

External abrasion resistance

Abrasion test comparisons of Vectran and aramid braids were conducted by a high-performance rope and cable company using the test shown. With or without marine finish on the braid, Vectran outperforms aramid materials.

Yarn-on-yarn abrasion resistance

Fatigue resistance can be measured using the rope and cordage industry standard known as the yarn-on-yarn abrasion test (i.e., The Cordage Institute test method CI-1503). This test simulates abrasion of adjacent yarns inside a rope or rope-splice during flexure. Using this test, the combination of wet and dry abrasion resistance by Vectran outperforms competitive materials like aramids and HMPEs.
