The effects of shear p lverization on themechanical, thermal and electrical properties of PP/CF compositesw ere investiga- ted. Themorphology of fract red s rface observed by scann ing electron m icroscopy( SEM ) ind icated that the shear p lverization ind ced by mechanochem ical reactor was efficient to enhance the homogeno s distrib tion of CF in PP matrix and red ced the voids existing in the composite, w hich w as favorable to the thermal and electric cond ctivity.
