Effects of Date (Phoenix Dactylifera-DPF) and Doum (Hyphaene Thebaica) Palm Natural Fibers Reinforced Polymer Matrix on Damage of Advanced Biocomposites Materials

Abstract

The present work aims to perform an extensive numerical study based on genetic algorithms and Weibull probabilistic approach to highlight the effect of date palm fiber (DPF), doum palm and alfa fibers on the fiber–matrix interface damage of date palm/epoxy, doum palm/epoxy, and alfa/epoxy biocomposite materials. The results obtained in this study coincide perfectly and in good agreement with very recent theoretical and experimental studies. Mehdi Jonoobi et al. found through experimental trials that date palm fibers can be used to improve the ductility of epoxy matrix, and the use of date palm fibers in an epoxy-based composite can improve epoxy strength according to the weight ratio of fiber used, in addition, Noora Al-Qahtani et al. found that the morphology of the composites was improved which present superior adhesion among the palm fiber and the polymer matrix. Thus, it is useful now to study the opportunity to promote date palm fiber in different development sectors to encourage industries to manufacture ecological products from the date palm which will be a candidate promoter for new technological applications.
