초록

This paper investigates the effect of plasma treatment of aluminum on the fracture toughness of aluminum/CFRP composites, The surface of the aluminum panel was treated by a DC plasma. The plasma treatment was carried out at volume ratio of acetylene gas to nitrogen gas of 5:5 and the treatment times used was 30 sec. The fracture toughness of plasma-treated aluminum/CFRP' composites was compared with that of untreated aluminum/CFRP composites and The fracture surface of aluminum/CFRP composites was compared with SEM. The results showed that fracture toughness of plasm-treated aluminum/CFRP composites was about 50% higher than that of untreated aluminum/CFRP composites.
