Abstract
The role of “resorcinol-hexamethylenetetramine-silica” bonding system in adhesion between silk fibre and nitrile rubber has been studied. Definite proportions of the three components of the bonding system vis-à-vis fibre loading are found to provide the optimum set of technical properties. Increase of fibre concentration in the composites causes an increase in hardness, tensile strength, tear strength, modulus, heat build-up, compression set at constant strain, abrasion loss, and restriction to solvent-swelling and a simultaneous decrease in some properties like resilience, compression set at constant stress and elongation at break. Ageing enhances the adhesion level and shows improved retention of strength properties of the composites. Increasing fibre loading in the mixes leads to a significant improvement in processing characteristics. Scanning electron microscopy studies of fracture surfaces obtained from tensile, tear, abrasion and heat build-up testing have been made in order to assess the failure mode.
