The study of NaOH soaking time on kenaf/glass fiber hybrid epoxy compositesis described in this work. Kenaf fiber and glass fiber were used as filler while the matrix used was epoxy. The kenaf fiber was treated with 3% of NaOH solution at different soaking time which were 3, 6 and 9 hours. The composite samples were produced using filament winding process. The samples were subjected to tensile testing (ASTM 3036) to determine the mechanical properties of kenaf filled epoxy composites and kenaf/glass fiber hybrid filled epoxy composites. The physical properties of the composite sample were analysed using water absorption test, density test and morphological of fracture surface of composites has undergone Scanning Electron Microscope (SEM).
