Plant-Derived Fiber-Reinforced Polymer Composites: The Impact of Compatibilizer on the Fundamental Characteristics and Degradation Properties
Abstract: By using compression molding, unidirectional polypropylene (PP) composites reinforced with banana fiber were created both with and without the use of stearic acid (SA) as a coupling agent. Four filler loading levels (10%, 20%, 30%, and 40% by weight) were employed during the composite manufacturing process, using raw banana fiber. The resulting composites underwent mechanical testing (tensile, bending, and impact characteristics). The ideal combination of mechanical properties was found in …
