    Abstract

    It is well-known that the high strength, high modulus fibres of Kevlar 49, [poly (p-phenylene terephthalamide)], have a wide range of industrial applications. Extensive data on the behaviour and properties of this fibre are available in literature. Recently, Morgan and Pruneda4 have shown from chemical analysis that impurities in the form of sodium salts are present in Kevlar 49 fibres and have discussed the effect of such impurities on fibre13; characteristics such as microvoid formation, moisture sorption, hydrolytic stability etc. In this communication, results of X-ray diffraction experiments13; are reported which provide further evidence for the13; presence of sodium salts in Kevlar 49 fibres.13;
