Abstract | In the present work, epoxy based composites filled with hybrid nano-SiO2 particles and short pitch based carbon fiber were prepared. Copolymer of styrene and maleic anhydride was grafted onto the nanoparticles prior to the compounding so that the nanoparticles can be covalently connected to the composites’ matrix through the reaction between anhydride and epoxide groups during curing. Consequently, the nano-SiO2/matrix interfacial interaction was enhanced. By evaluating slidingwear properties of the composites as a function of the components concentrations, positive synergetic effectwas found. That is, both wear rate and friction coefficient of the hybrid composites were significantly lower than those of the composites containing individual nano-SiO2 or short carbon fiber. The composite with 4 wt.% nano-SiO2 and 6 wt.% carbon fiber offered the greatest improvement of the tribological performance. Compared to the results of hybrid composites reported so far, the above composite is characterized by relatively lower filler content, which would facilitate processing in practice.
