“…The improvement in mechanical properties can be attributed to the fact that the bleaching reaction leads to the fibrillation of the fiber bundle, i.e., breaking down of fiber bundles into smaller fibers, and thereby increases the effective surface area available for contact with the PLA matrix. Bleaching also improves the fiber surface adhesive characteristics by removing lignin and other impurities (Mukherjee et al 1993). The influence of the acetylation of jute fabrics on the mechanical properties of acetylated jute fabric/PLA composite is shown in Table 3.…”

Biocomposites based on poly(L-lactic acid) (PLA) and non-woven jute fabrics (NWJF) were fabricated by sandwiching non-woven jute mat between PLA sheets. First, composites were fabricated with various weight proportions of jute fabric (5, 10, 20, and 30 wt.%) with the PLA matrix, and the effect of fabric loading on their mechanical properties was investigated. Higher mechanical properties were found at 10 wt.% fabricloaded composite. The results show that the tensile, flexural, and impact strengths were increased by 61.7, 52.3, and 47.2%, respectively, as compared with neat PLA. In the second part, the jute fabrics were chemically treated with NaOH, NaClO2, acrylonitrile, acetic anhydride, KMnO4, diphenylmethane diisocyanate, and benzoyl chloride. The effect of chemical treatment on the mechanical and water absorption properties of NWJF/PLA biocomposites was studied. The mechanical properties of these biocomposites were found to be higher than those of untreated biocomposites. Among all the treatments, the combined alkalibenzoylated-treated fabric composite showed higher mechanical properties. The water absorption properties of these composites were found to be remarkably lower than those of untreated fibers. The interfacial adhesion between the fiber and the matrix was shown to increase with surface modification as revealed by SEM analysis.

“…Mukherjee et al, (1993) reported that the removal of hemicellulose produces less dense and less rigid interfibrillar region. Kokot et al, (1995) also noted that as lignin is removed, the middle lamella joining the ultimate cells is expected to be more plastic as well as homogeneous, due to the gradual elimination of microvoids.…”

“…The improvement in the tensile strength in the case of bres treated with alkali of higher concentration can be attributed to the following reasons: (1) Due to alkali treatment, the cementing materials get dissolved. The inter brillar region becomes less dense and and less rigid and the brills become more capable of rearranging themselves along the tensile deformation [15]. Other Table 2.…”

Among the various factors, the nal performance of the composite materials depends to a large extent on the adhesion between the polymer matrix and the reinforcement and therefore on the quality of the interface. To achieve optimum performance of the end product, suf cient interaction between the matrix resin and the cellulosic material is desired. This is often achieved by surface modi cation of the resin or the ller. Banana ber, the cellulosic bers obtained from the pseudo-stem of banana plant (Musa sepientum) is a bast ber with relatively good mechanical properties. The ber surface was modi ed chemically to bring about improved interfacial interaction between the ber and the polyester matrix. Various silanes and alkali were used to modify the ber...
