Waste Silk Yarn Reinforced Epoxy Laminate

Abstract

Fibre reinforced composites have gained popularity nowadays because of their processing advantages and good technical properties like strength, stiffness, elastic modulus ,creep rate, damping. These properties were found to increase with silk fabric content. Waste silk fabric reinforced epoxy laminates were developed with varying content of silk. silk fibre because of the presence of many functional groups like –NH2-,COOH,NHCO,CH2OH on its surface is polar in nature .This fibre has got a non-cellular structure in contrast to other natural fibre like jute and cotton.The above characteristic of fibre and polymer are expected to produce excellent adhesion between silk fibre and polymer in their composite.The importance of fibre reinforcement in production of hoses ,v-belts and the manufacture of complex shaped mechanical goods. Apart from that specially tailored lightweight structural parts with continuous fibre reinforcements, biocomposites are very well suited for panelling elements in cars, railways and aeroplanes, etc. using different kinds of nonwovens from single fibres (needlefelt nonwovens, fleeces etc.) to be easily adapted to the usually curved shapes of panellings, fairings etc.
