Fiber-reinforced plastic corrugated core sandwich panels were tested for low velocity impact using drop test method. Three types of epoxy based corrugation i.e sinusoidal, square and triangle of different core thickness and height of the drop were tested. The paper focused to development of statistical equations using multiple regression analysis, correlating various process parameters to responses udsuch impact load, energy and deflection of the impacts. udThe experiments were conducted based on three factors and three levels (full factorial). The model adequacy was checked by Analysis of variance (ANOVA). The main effect and interaction effects of the impact parameters on responses were studied using contour plots. The correlation was obtained by multiple-variable linear regression using Minitab14 software. Analysis of the influences udof the entire individual input impact parameters on the responses has been carried out and udsignificant contribution of parameters is determined by analysis of variance (ANOVA).
