Experiments are described in which single fibres, embedded in a polyester resin, were immersed in water at various temperatures for various times, and the fibres then pulled out. The effect of the water on the polymer was also investigated. It was found that the fibre-polymer bond strength was reduced almost to zero after 400 h in 75 o C water, but at 60 o C the reduction was only 40%-50%, even after 13 000 h immersion and at 22 o C the strength was reduced by 20% after 13 000 h immersion
