Experimental study reveals damage mechanisms in glass and carbon fiber composites under high-velocity water impact, highlighting key material variables that dictate rain erosion resistance.
The impact properties of composites of glass fibre or carbon fibre in polyester or epoxy resin were studied. Impact was by high-velocity water jets ( approximately 700 ms -1 ), which previous work has shown successfully simulate rain erosion damage and other impact situations involving high-stress (of the order of 1 GPa) and short-duration (few mu s) loading. The failure of the composites is analysed and the damage mechanisms are identified. An assessment is made of the effect of such variables as reinforcement geometry, volume fraction of fibres, matrix toughness, void content and surface condition.
