dc.description.abstractEpoxy resin is an important matrix resins for thermosetting polymer composites. The objectives of this study were to extracts and characterize lignin from black liquor to be used as curing agent in epoxy resin application. Lignin obtained from pulping of oil palm biomass empty fruit bunches (EFB) fibers, were used as curing agent in green epoxy composites. The chemical structures and properties of lignin were confirmed by CHN analyses, FTIR, GPC and thermal analysis. Epoxy-lignin composites, with varying lignin content (15%, 20%, 25% and 30%), reinforced with EFB fiber were prepared. The effect of EFB based lignin on thermal and morphology properties of the composites were investigated and compared with the composites cured with isophorone diamine curing agent. The mechanical and physical properties such as tensile, flexural, impact properties and water absorption of EFB reinforced epoxy-lignin composite were also studied. The improved thermal stability and the observed microstructure of the fractured surface of the composites were attributed to good fiber-matrix interaction, induced by the curing agent. In general, the results showed that the epoxy reinforced EFB composites cured with 25% lignin content proved to be a better matrix and gave optimum value compared with other formulations which was confirmed by its mechanical, thermal and morphological properties.en_US
