Optimization of surface treatment to enhance fiber-matrix interface and performance of composites

► HNO3 treatment (30-180 min) to carbon fabric led to changes in surface topography. ► Treatment proved beneficial for adhesive wear performance of composites. ► 90 min treated CF composites (C90) showed highest strength properties. ► Highest wear resistance and lowest μ was observed for C90 composites. ► A good correlation was observed for wear resistance and ILSS of composites.
