Study on Chemical Treatments of Jute Fiber for Application in Natural Fiber Reinforced Composites (NFRPC)

Research and studies on the use of natural �bers as replacement to man-made �ber in �ber-reinforced composites have increased and opened up further industrial possibilities. Natural �bers have the advantages of low density, low cost, biodegradability, recyclable, low pesticide and thus environmentally friendly. However, the main disadvantages of natural �bers in composites are the poor compatibility between �ber and matrix and the relative high moisture sorption. Therefore, chemical treatments are considered in modifying the �ber surface properties. In this paper, the different chemical modi�cations and treatments on jute �bers for use in natural �ber-reinforced composites are reviewed. Chemical treatments including alkali, permanganate treatments and others are discussed. The chemical treatment of �ber aimed at improving the adhesion between the �ber surface and the polymer matrix may not only modify the �ber surface but also increase �ber strength. Water absorption of composites is reduced and their mechanical properties are improved.
