The effect of ultraviolet radiation on the tensile properties of two engineering fibres, namely Kevlar 149 and Technora, is reported. Both fibre types show considerable loss in strength, but the former also exhibits a significant and unexpected fall in modulus. Electron microscope examination of the virgin and extended fibres revealed the structural reasons for the observed mechanical behaviour.
