摘要: The tribological and electrical properties of epoxy composites filled with nano-sized silica particles are studied discussed in this article. To enhance the interfacial interaction between fillers matrix, nanoparticles were pretreated silane coupling agent. Dry sliding wear tests carried out configuration composite sample on a rotating steel disc. Electrical measurements such as AC breakdown voltage, at 50 Hz, high voltage-low current arc resistance wet tracking out. results reveal influence nanosized loading epoxy. It is observed that 10 wt% very effective reducing loss. With further increase filler loading, agglomerated resulted specific rate. rate more pronounced under situation. particle evident parameters like dielectric strength, resistance. These showed improvement up to 15 beyond value noticeable deterioration was observed. effects stresses morphologies surfaces nanocomposites discussed. POLYM.
