Abstract: Flyash does not contribute to properties of composites and hence there are severe limitations on its use as a filler. The paper reports determination and discussion on mechanical properties of SBR composites filled with flyash (treated and untreated). The flyash was treated with a silane coupling agent (TESPT) [Bis (3-triethoxysilylpropyl) ] tetrasulphide. The treatment resulted in enhancement of mechanical properties of composites of the rubber. In this work, properties of composites filled with treated and untreated flyash (separately) are compared. The properties under consideration were tensile strength, modulus at 100 and 400 per cent elongation, and hardness. Tensile strength was improved by 20 per cent while modulus at 100 per cent was improved by 30 per cent. Similarly Young’s modulus also was improved by 22 per cent.
