Abrasion Resistance of Polybenzimidazole Fibrous Materials.
Abstract
An improved method of evaluating in the laboratory the simulated wear resistance of both monofilaments and staple yarns is described. Wear resistance is measured as a fraction of strength retained after abrasion against a solid PBI bar. The coefficients of variation in wear resistance findings are shown to be compatible with the coefficients of variation in tensile strength data of unabraded control specimens. (Author-PL)
