Natural rubber and styrene butadiene rubber (NR/SBR) reinforced with short nylon fibres along with nanoclay (Cloisite 15A) hybrid composites were prepared in an internal and a two roll-mill mixer by a three-step mixing process. The effects of fibre content at a constant loading of 3 wt% nanoclay were studied on the microstructure, mechanical properties of the prepared nanocomposites. The adhesion between the fibre and the rubber was enhanced by the addition of a dry bonding system consisting of resorcinol, hexamethylene tetramine and hydrated silica (HRH). X-ray diffraction results of nanocomposites indicated that the interlayer distance of silicate layers increased. The mechanical properties (tensile, tear strength, elongation-at-break and hardness) of nanocomposites containing virgin and waste fibres in the longitudinal direction are compared
