Abstract
In the present study, lignocellulosic-epoxy composites were prepared from Kenaf bast fiber at different loadings using resin infusion method. Montmorillonite (MMT) was used as a filler which would be mixed in the epoxy resin before the mixture (resin, hardener and MMT) was infused to the Kenaf fiber mat. The effect of modification on MMT was also studied in this work. MMT was modified using grafting process, which the oxygen in MMT were grafted with isocyanates group from Hexamethylene Diisocyanate (HMDI). The mechanical properties of the composites prepared were improved as Kenaf fiber loadings increased. This indicated that the reinforcement effect by additional of Kenaf fiber was evident. The mechanical properties of the composite can be further enhanced by additional of MMT or HMDI-MMT.
