Effect of silica and silica gel with natural rubber composites was studied through mechanical properties and morphological studies. In this work, natural rubber blends with carbon black (CB) and silica as composite material-1 and natural rubber blends with CB and silica gel as composite material-2 were synthesized by two-roll-mill process followed with hydraulic press at specified operating conditions. These composite materials were investigated with each other in different proportions of sample with regard to the tensile strength, tensile modulus, and elongation at break, tear strength and hardness. The composite material-1 found to be a greater improvement in the physical properties in comparison with the composite material-2 in all same proportions. Morphology results revealed that silica adding up composites had strong interfacial adhesion and uniform dispersion into the rubber matrix, whereas silica gel had weak adhesion and improper dispersion. Comparison study also carried out with virgin natural rubber vulcanizates. Based on results, silica could be a suitable filler material than the silica gel for improving natural rubber composites performance in the basis of reliability and durability.
