Banana Fiber-Reinforced Polypropylene Composites: A Study of the Physico-Mechanical Properties

Banana fiber-reinforced polypropylene (PP) matrix composites were prepared by compression molding and their mechanical properties were evaluated. Banana fibers and matrices were irradiated with UV radiation at different intensities. Mechanical properties of irradiated banana fibers and matrices based composites were found to increase significantly compared to untreated counterparts. Optimized banana fibers were treated with 2-hydroxyethyl methacrylate (EMMA) solution and were cured in an oven at different temperatures for different curing times and then composites were fabricated. Monomer concentration, curing temperature and curing time were optimized with the extent of polymer loading and mechanical properties and showed better mechanical properties over untreated composites. Water uptake and simulating weathering test of the composites were also investigated.
