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.
