Abstract: Interlayer slip is an important forming mechanism for the thermal deformation process of thermoplastic composite parts. The study of the interlayer slip behavior of prepreg is the basis for the prediction and control of wrinkle defects in hot deformed composite parts. In this paper, the sliding behavior of continuous carbon fiber reinforced polyphenylene sulfide prepreg during hot deformation molding is studied. Using a self-designed test system, the sliding behavior of satin fabric prepreg and unidirectional prepreg is characterized. And the influence of temperature, normal pressure and speed on the slip behavior are considered. The results show that increasing the test temperature, lowering the pulling speed and normal pressure are conducive to the movement of the fibers and promote the interlayer slip deformation of the prepreg. The Stribeck model is used to predict the interlayer friction coefficient of continuous carbon fiber reinforced polyphenylene sulfide prepreg and compare it with the experimental results. The results show that there is a linear relationship between the Hersey number and the friction coefficient.
