ABSTRACT

This chapter discusses different types of composites, processing and their biodegradation studies. Polymer composites have been used in various applications, such as automotive, aerospace, construction and packaging; and their market is growing immensely. The composite reinforced with alkali-treated hemp fabrics displayed lower tensile strength and modulus as well as lower flexural strength and modulus in comparison with composites reinforced with untreated hemp fabrics. Synthetic polymers reinforced with natural fibres have been extensively used in packaging and automotive applications. Composite is an emerging area, and it offers an opportunity to replace synthetic products made from petroleum-based resources. The reason for slower degradation of biocomposites could be due to the addition of crystalline cellulose nanofibres which delays biodegradation. The crystallinity of biocomposites increased with an increase in exposure time, which could be due to the degradation in the amorphous regions by microorganisms.
