Predicting the effect of coconut natural fibers for improving the performance of biocomposite materials based on the poly (methyl methacrylate)-PMMA polymer for engineering applications

The choice of materials depends on the performance requirements of the system and many other factors including size, weight, mechanical load, environment, number of systems required, and cost. In this context, we have studied and investigated, using the genetic approach and the nonlinear acoustic technique, the effect of mechanical and thermal stresses on fiber–matrix interface damage of E-Glass/Poly (methyl methacrylate)-PMMA and Coconut/PMMA composite and biocomposite material, respectively. The results of the genetic modeling are in good agreement with the nonlinear acoustic technique results. We have found a difference in fiber–matrix interface damage between the two materials Coconut/PMMA and E-Glass/PMMA is in the order of 0.02–0.09. The results of statistical analysis based on the values ​​of the correlation coefficients, which are very nearly to 1 (0.9991 and 0.9938), have proved the convergence of genetic results. This finding confirms the conclusions found by several researchers where they have showed that coconut fibers are potential candidates for the reinforcement of civil engineering structures, in building materials and wireless communication devices due to their better physical and mechanical properties, and that coconut fiber can be a potential candidate to partially replace glass fiber in certain areas mentioned above and confirmed by very recent and interesting studies dated in 2020 and 2021.
