Abstract

The damage caused by the impact of high velocity water jets (100 to 1200 m sec-1) on GFRP specimens from a prototype Concorde radome has been investigated. The dependencies of the extent of various damage modes on the jet velocity, size and angle of impact have been studied in detail. The effect of multiple impacts has also been examined. The results are interpreted in terms of the fundamental deformation and failure mechanisms of a composite system. The results show that damage is sensitive to the size and velocity of the impacting jet and that more damage may occur for oblique impact than for normal impact. The liquid jets model impact by spherical drops and the conclusions are therefore relevant to the case of rain erosion.
