Abstract
Natural fibre and nano-filler-based composites are gaining popularity because of their high strength, recyclable nature, high strength-to-weight ratio, and other benefits. The primary goal of this study is to maximize the many factors that influence the mechanical characteristics of hybrid nanocomposites. The nanocomposites were created using the standard hand lay-up method with the following conditions: (i) fibre content, (ii) length of pineapple fibre in mm, (ii) weight proportion of nano SiO 2 ; and (iii) alkali treatment periods. Following manufacture, the composite's mechanical characteristics were tested according to ASTM standards. Quantitative optimisation using the Taguchi technique Depending on the S/N ratio of Taguchi refinement, the nanocomposite with the maximum mechanical performance contains 20 % pineapple fibre with a length of 10 mm, 5 % nano SiO 2 , and 6 h of NaOH treatment. The ANN predictive algorithm and the Taguchi L 27 array show that the experiment and projected data for tensile, flexural, and impact are within 3 % and 4 %. According to the ANOVA study, the NaOH approach provides around 45 %, followed by the pineapple fibre content of 25 %, fibre length of 20 %, and filler content of 5 %. The similarity between artificial neural networks and test findings expands the scope of ANN for forecasting strength properties. This approach will assist designers in predicting system failures concerning the operating duration and may be utilised in numerous industrial industries to analyse toughness attributes.
