Stressed Fabric Abrasion Test Procedure for Urethane Coated Fabric Fuel Tanks

摘要

This report details investigations conducted and results obtained in efforts to develop a test procedure for measuring the effects of abrasion under stress in urethane-coated fabric tanks. The Rubber and Coated Fabrics Research Group, Materials, Fuels and Lubricants Directorate, Belvoir Research, Development and Engineering Center, prepared all samples from material submitted by coated fabric suppliers, performed all tests, and documented results. Four different urethane materials were tested on the Taber Abrader which was modified to test the fabric under stress. The urethanes showed a marked decline in the ability to withstand abrasion while under stress. Keywords: Abrasion; Urethanes; Collapsible tanks; Protective coatings. (jes)
