The results of experimental studies of the effect of an electric discharge on carbon fiber in the discharge voltage range U = 0.2 - 1300 V and at a current I = 0.03 - 1.8 A, at atmospheric pressure are presented. Some features of the combustion of an electric discharge with liquid electrodes are revealed. Some features of the effect of an electric discharge on carbon fiber have been established.

In this work, experimental reseaches of the effect of a DC electric discharge with jet electrolytic cathode and liquid anode at atmospheric pressure on carbon fiber are carried out. Experimental studies were carried out in the voltage range U= 100-1300 V and discharge current 1=0.02-1.8 A. A 20% NaCl solution in process water was used as liquid electrodes. The length of the jet varied lc = 10÷50 mm, the diameter of the jet dc = 1÷3 mm. The optimal form of discharge and modes for processing carbon fiber have been established. The optimal mode of electric discharge which is between a jet electrolytic cathode and a liquid anode at atmospheric pressure is revealed. After processing for 30 s, the tensile strength of the modified samples changed by 7% compared to the untreated sample.
