Abstract:

The study focused on the use of response surface methodology to predict the optimal tensile response of wood ash particles /polypropylene combination for auto part (car bumper) design. Taguchi plan of experiment based on L9(3)4 was used to design the experiment. The data obtained from the experiment were analyzed using S/N ratio and mean of means as the statistical measure of performance. The response surface and contour plots show the optimized responses of individual interactions in the range of > 13.50MPa - > 19.50MPa. The contour and surface plots depict the behaviour of the tensile strength as two input variables vary and two held constant at their highest settings). The tensile strength of WARPP is in the range of 17.08MPa - 21.19MPa. The highest tensile strength value was obtained by simultaneous optimization of input variables depicted in optimization plot of figure 15 as 21.19MPa. Further investigations are recommendable for testing WARPP under high temperature for the design/formulation of auto part (car bumper) to ascertain its performance at elevated temperature.
