THE EFFECTS OF ELECTRIC ON THE IMPACT DAMAGE CHARACTERISTICS AND RESIDUAL COMPRESSIVE STRENGTH OF ELECTRIFIED CFRP COMPOSITES

Abstract

Abstract: The electric-thermal damages were studied in the paper and are performed on carbon fiber reinforced polymer (CFRP), the surface temperature field of electrified CFRP specimens was measured by the self-devised damage test device. The resistance variation with current magnitude was measured for the CFRP composites. When comparing the initial resistances at the onset of the electric current applications for the same specimen subjected to the currents of different magnitudes, it was found that resistance decreased with an increase in the current magnitude. We have also investigated experimentally the influence of the current application on the impact response of CFRP. The relationship between damage area, compressive strength after impact (CAI) and current magnitude was discussed. The major damage mechanism of electrified composites under compressive load was also analyzed. It was demonstrated that the current density plays an important role in the impact damage resistance of electrified composites: in contrast to a low current application that has almost no effect on the CAI of the tested composite, a stronger application of an electric current apparently had a detrimental effect on the composites. The dent depth and impact area increases rapidly with the increasing of current after 20A.
