Continuous carbon reinforced aluminum matrix composites were prepared through electromagnetic forming technology to improve serious interface reaction

long preparation period and high device requirement in traditional methods.The effects of discharge voltage on microstructure and mechanical properties of the composites prepared by the optimized parameters

such as the preheating temperature of carbon fiber of 380 ℃

smelting temperature of aluminum alloy of 900 ℃ and heat preservation temperature of 750 ℃.The results reveal that with the charging voltage of 2 500 V
