Abstract
This research aims to enhance the mechanical performance of Baobab pod fibres (BPFs) nanocomposite through the utilization of response surface methodology (RSM). Box-Behnken module of response surface methodology (RSM) available in “Design Expert® Version V13” was used to establish design matrix, optimize treatment conditions and analyze experimental data. For the optimization, DOE was created using the box Behnken technique in, in which three input parameters (NaOH concentration, soaking time and soaking temperature) and one response parameter (Tensile strength) were used. Further before the optimization, analysis of variance (ANOVA) test was performed and the model was found significant for the response. The optimization of chemical treatment of fibre predicts solution for NaOH concentration at 6.963, soaking time of 359.9. Acid hydrolysis was then used to produce cellulose nanocrystals from the treated fibres. The fibre reinforced composites were produced using compression moulding technique. After composite fabrication, specimens of standard size were prepared, and test related to mechanical properties were performed. Sample C composites performed best in tensile strength. The flexural value test value for composite B was the highest. It was also found that composite C had the best hardness.
