Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different parameters including fiber loading, type of nano powder and its weight percentage and also weight percentage of NaOH in alkali treatment were analyzed. Optimization was also performed using Taguchi L8 orthogonal array. Moreover, analysis of variance (ANOVA) was conducted to determine the significance of the parameters. In this study, finite element model was also created in ABAQUS software to compare with the results obtained from the experiments to achieve validated finite element model. There was a good agreement between the results from experiments and those obtained in numerical simulations.
