Polyurethane (PU) composites were prepared utilizing palm kernel oil-based (PKO) polyurethane as the matrix and oil palm empty fruit bunch fiber (EFB) as the filler. The bio-composites were prepared both by molding for 20 minutes at ambient condition and hot-pressing at 35 °C for 9 minute with a load pressure of 760 MPa. The former was carried out by initially determining type of surface modification of EFB required. Treatment with 5% sodium hydroxide, silane and...
