Kenaf (Hibiscus cannabinus L.) is one of the most investigated and industrially applied natural fibers for polymer composite reinforcement. However, relatively limited information is available regarding its epoxy composites. In this work, both thermal and chemical properties were, for the first time, determined in kenaf fiber reinforced epoxy matrix composites. Through XRD analysis, a microfibrillar angle of 7.1° and crystallinity index of 44.3% was obtained. The FTIR analysis showed the functional groups normally found for natural lignocellulosic fibers. TMA analysis of the composites with 10 vol% and 20 vol% of kenaf fibers disclosed a higher coefficient of thermal expansion. The TG/DTG results of the epoxy composites revealed enhanced thermal stability when compared to plain epoxy. The DSC results corroborated the results obtained by TGA, which indicated a higher mass loss in the first stage for kenaf when compared to its composites. These results might contribute to kenaf fiber composite applications requiring superior performance.

“…The carboxyl group (-COOH) is supposed to react with the hydroxyl groups of the fiber through an esterification reaction and, hence, the treatment should reduce the number of hydroxyl groups available for bonding with water molecules. Furthermore, the long hydrocarbon chain of stearic acid (18 carbon atoms) provides an extra protection from water due to its hydrophobic nature [43].…”

Four different strategies for mitigating the highly hydrophilic nature of flax fibers were investigated with a view to increase their compatibility with apolar polypropylene. The effects of two carbon nanostructures (graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs)), of a chemical modification with a fatty acid (stearic acid), and of maleated polypropylene on interfacial adhesion, mechanical properties (tensile and flexural), and thermal stability (TGA) were compared. The best performance was achieved by a synergistic combination of GNPs and maleated polypropylene, which resulted in an increase in tensile strength and modulus of 42.46% and 54.96%, respectively, compared to baseline composites. Stearation proved to be an effective strategy for increasing the compatibility with apolar matrices when performed in an ethanol solution with a 0.4 M concentration. The results demonstrate that an adequate selection of surface modification strategies leads to considerable enhancements in targeted properties.

“…Kenaf fiber is one of some natural fibers used as the reinforcement of the thermoplastic composites [4] for automotive application due to its high tensile strength of the fiber [6]. Besides, it is abundantly available in this earth, especially in Asia [5] including Indonesia. Toyota Boshoku Corporation, Japan becomes a pioneer in using kenaf as a raw material for the interior automotive components [6].…”

Kenaf/E-glass reinforced polypropylene (PP) hybrid composites with different fiber loading 20, 25 and 30 (vol. %) were fabricated using a hot compression molding. The effect of the fiber content on the tensile properties of the composites was studied. The ratio of alkali-treated kenaf fiber and untreated E-glass fiber was 20:10 (vol. %). The tensile strength and strain of the composites slightly decreased with the increase of the fiber content, but tensile modulus increased. The presence of voids and inhomogeneous distribution of the fibers led to the change of tensile properties of the composites as confirmed by scanning electron microscopy (SEM) micrographs of the tensile fracture surface.
