The effects of test parameters on the impact response of glass reinforced plastic using an experimental design approach

An instrumented falling weight machine was used to investigate the effects of test parameters on the impact response of low fibre-volume E-glass woven-roving reinforced polyester coupons. Statistical experimental design techniques were used to plan the experiment and to analyse the data. All the parameters considered were found to affect the responses in a complex and interacting manner. Multiple damage modes occurred and the damage mechanisms...
