Biocomposites reinforced with bagasse fibre were prepared by a hot press forming, and the effects of fibre volume fraction, fibre length and alkali treatment on the flexural properties of composites were investigated. The flexural properties of the composites increased with the increase in fibre volume fraction to an optimum fibre volume fraction of 65%. SEM micrographs revealed that the compressed cellulose structure of the bagasse fibre could have contributed to the improvement in the properties. The flexural properties of the composites increased with the increase in the fibre length, however, decreased below the critical fibre length. Furthermore, comparing the effects of different alkali treatments to the fibre, the 1% NaOH treated fibre composites showed maximum improvement in the flexural properties. After alkali treatment, the fibrillation occurred and the surface of the fibres got finer could contribute to the improvement in fibre-matrix adhesion, and result in enhancing the flexural properties. |
