PALF was pretreated with sodium hydroxide (PALF/NaOH), cellulase enzyme treatment and modified with N-2(aminoethyl) 3-aminopropyl trimethoxysilane (PALF/silane) to improve interfacial strength of the composites. PALF with different surface treatment methods were characterized using Fourier Transform Infrared and Scanning Electron Microscopy technique. The composites were tested mechanical properties by Universal Testing machine. The results show that the modified PALF composites lead to the enhancement of mechanical properties such as young's modulus. Young's modulus is the highest for PALF/NaOH/Cellulase composites. PALF/silane composites possessed the highest tensile strength and impact strength among all the treated system.ABSNatural fiberSurface treatmentConference paperScopus
