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.
External abrasion resistance, marine applications
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.
