Optimizing Filler Loading and Particle Size for Enhanced Physico-Mechanical Properties in Peanut Shell

Abstract

The extensive application of synthetic fiber-reinforced polymer composites is prone to dwindling due to their substantial upfront expenses, chief among them being their detrimental effects on the environment. Researching the possible application of natural fibers as polymer reinforcement is one of the main priorities. Thus, natural fiber composites which are made of natural or synthetic resins and reinforced with natural fibers—have drawn the attention of researchers. In this work, new types of polymer matrix composites reinforced with peanut shell particles treated with alkali (NaOH) are processed in epoxy, vinyl ester, and polyester resin matrices, and their mechanical and physical properties are characterized. The results of the parametric study show that resin, filler weight percentage, and particle size all contribute significantly to improving the suggested properties of composites.
