Abstract
The structural changes which accompany decomposition of Kevlar 49 fibres at T= 500xB0;C: and 550xB0;C, respectively, have been elucidated. At both these temperatures, cumulative thermal exposures of specific durations, tcum{T}, are required to result in decomposition. The conspicuous features which characterize isothermal decomposition of the fibres are: (i) progressive reduction and an eventual total loss in fibre crystallinity, (ii) progressive loss in weight, (iii) introduction of surface damages, (iv) introduction of hollowness, and (v) deterioration in tensile properties.
