     this paper discusses the friction and dry sliding wear behaviour of nano-zirconia (nano-zro2) filled bismleimide (bmi) composites. nano-zro2 filled bmi composites, containing 0.5, 1, 5 and 10 wt.% were prepared using high shear mixer. the influence of these particles on the microhardness, friction and dry sliding wear behaviour were measured with microhardness tester and pin-on-disc wear apparatus. the experimental results indicated that the frictional coefficient and specific wear rate of bmi can be reduced at rather low concentration of nano-zro2. the lowest specific wear rate of 4 × 10−6 mm3/nm was observed for 5 wt.% nano-zro2 filled composite which is decreased by 78% as compared to the neat bmi. the incorporation of nano-zro2 particles leads to an increased hardness of bmi and wear performance of the composites shows good correlation with the hardness up to 5 wt.% of filler loading. the results have been supplemented with scanning electron micrographs to help understand the possible wear mechanisms.
