✦ Synopsis

The interfacial degradation in a model composite of an aramid fibre (Kevlar 49) and unsaturated polyester (UP) followed by absorption and desorption of hot water at 90 • C was monitored by measuring the variations in residual stress in the embedded fibre by means of the micro-Raman technique. The Fourier transform infra-red (FTIR) microspectroscopic analyses were also conducted to study the structure and the quantity of absorbed water causing interfacial degradation.
