Cryogenic treated multilayered carbon fabric/oxidized multiwall carbon nanotube/epoxy (CCF/O-MWCNT/E) composite and untreated carbon fabric/epoxy (CF/E) composite were prepared by hot compression molding technique. The density and mechanical properties such as tensile properties, flexural properties, interlaminar shear strength, and microhardness of the compositeswere investigated as perASTMstandards.Thewear and coefficient of friction behaviorwere investigated using computer interfaced pin-on-disc test rig at room temperature for varied load and sliding speed.Themorphology of worn surfaces of the wear test composite specimens were studied by scanning electron microscope. It is found that the synergetic effect of addition of OMWCNT to epoxymatrix and cryogenic treatment of carbon fabric improved the wear resistance andmechanical properties. Also, a thin lubricating film developed by the oxidized multiwall carbon nanotube/epoxy wear debris reduces the coefficient of sliding friction and wear rate.
