摘　　要：对碳纤维预浸料超声切割工艺进行了研究。在超声切割过程中 ,为了保证切割质量 ,对切割压力仍有一定的要求。超声切割功率的提高 ,有利于减小切割压力 ,拓宽切割速度范围。实验结果表明 ,对于纤维预浸料的切割与下料 ,超声切割技术是一种可获得高质量、高效率的加工方法。In this paper, the ultrasonic cutting technology of prepeg is studied.In ultrasonic cutting process, the cutting pressure is still essential for achieving good quality cut edge compared with traditional mechanical cutting process. With the increase of the cutting power, the cutting pressure demand decreases. And the cutting velocity range is extended broadly. The experiment results show that ultrasonic cutting technique is an effective, clean and controllable method for machining of carbon fibre prepreg.$$$$
