Impact Strength of Coir Fiber/Boron Nitride/Fly Ash Fortified Epoxy Composite

The coir fiber, boron nitride and fly ash-reinforced epoxy polymer composites were fabricated for testing and analysis. The design of the experiment method of response surface methodology (RSM) is considered to prepare the specimens. Central composite design, a model available in RSMб was used to obtain different composition of specimens. The significance of reinforcing parameters like wt% of coir fiber, boron nitride, and fly ash on the impact energy of composite were investigated by performing an analysis of variance (ANOVA). The regression equation, obtained by means of ANOVA reveals that the wt% influence of the coir fibers is more significant than that of boron nitride and fly ash. Optimization study was carried out to determine the combination of optimized parameters to get maximum impact energy. The confirmation experiment validates the optimization study.
