Development of a Test Method to Evaluate Textile Wear Resistance
Abstract
The oscillating motion of the new test apparatus development under this work effort, when combined with an abrasive media, produces a large (15x15) uniformly abraded material. The abraded material, can then be cut into several test specimens to characterize and provide a quantifiable means of evaluating the physical properties (tensile strength, tear strength etc.) and performance of the abraded fabric by comparing it directly to unabraded fabrics and/or other fabrics to aid in downselecting the best material. The versatility of the tester allows it to accommodate a wide variety of materials as well as abrasive media in order to simulate various environmental and/or operational conditions. The use of ceramic bevels or synthetic rocks (to simulate an urban or subterranean environment) were found to be an effective media in abrading standard textile fabrics. Three fabrics (ACU, FRACU and A2CU) were subjected to a limited amount of timed abrasion tests ranging from 30-360 min. All three fabrics exhibited significant changes in their warp tensile strength properties after 30 min of testing and continued to degrade through the 360 min tested. This testing suggests that a visual evaluation of abraded material after testing, or using a rupture in fabric yarns or hole formation as the fabric's end point is not an adequate assessment of the abrasion resistance of the fabric or the effect of abrasion on the fabrics performance. The large uniformly abraded area produced during this testing provides a unique advantage over other abrasion testers and provides the opportunity to quantifiably assess the performance of abraded fabrics, a capability which previously did not exist.
