BMI　resin/graphite　oxide　nanocomposites　were　prepared　via　a　solution　intercalation　method.　The　structures　of　the　nanocomposites　were　studied　using　Fourier　transform　infrared　spectroscopy　(FT-IR),　X-ray　diffraction　(XRD),　transmission　electron　microscopy　(TEM),　and　scanning　electron　microscopy　(SEM).　The　mechanical　and　tribological　properties　of　the　nanocomposites　were　investigated.　In　addition,　the　thermal　behavior　of　the　nanocomposites　was　characterized　by　thermogravimetric　analysis　(TGA).　Results　show　that　BMI　resin/graphite　oxide　exfoliated　nanocomposites　were　successfully　prepared.　The　addition　of　graphite　oxide　is　beneficial　to　improve　the　mechanical　and　tribological　properties　of　the　nanocomposites.　Moreover,　the　nanocomposites　obtained　exhibit　good　thermo-stability　in　comparison　with　neat　BMI　resin.　©　2010　Elsevier　Ltd.　All　rights　reserved.
