Experimental verification of failure of Amontons' law in polymeric textiles

Abstract

Abstract The dynamic friction of a variety of textile materials was studied and was experimentally proven that the frictional behavior of textile materials do not obey the Amontons' basic law of friction ( F / N = μ). Both woven and nonwoven materials with different fiber content and constructional features were used in the study. Results show that the dynamic friction–normal load relationship is not a straight line passing through origin. A statistical approach has been followed to prove the significance of the deviation from the Amontons' law. To the authors' best knowledge, the work reported in this article has for the first time experimentally proven the failure of Amontons' basic law of friction for polymeric textiles, using a novel approach. © 2004 Wiley Periodicals, Inc.
