Abstract

Ultrasonic cutting for prepreg slabs, with no tool wear, fast processing speed, high precision, no dust pollution, and other advantages, has been widely applied abroad for its excellent cutting quality, while in China the technology is still at an early stage of application. This paper presents a preliminary study of the influence of cutting temperature, cutting speed and cutting energy in the ultrasonic cutting process on cutting quality using carbon fiber prepreg as the experimental material. This study shows that for thick prepreg slabs with a certain thickness, the optimal cutting process parameter combination is for the cutting temperature to be 5℃, cutting speed to be 1.0 m·min^-1, and cutting energy at level eight. This study can provide some ground work for the application of the technology of ultrasonic cutting for prepreg.

Key words： ultrasonic cutting; thick prepreg slab; cutting temperature; cutting speed; cutting energy
