Based on the analysis of automatic tape laying (ATL) process, this paper introduces temperature in the process of ATL, aiming at bettering the control of ATL. Under a certain pressure and velocity, this paper proposes a theoretical calculation based on thermal elastic deformation to predict prepreg deformation, according to the influence of temperature on fluidity of prepreg in the process of ATL. Then through ATL experiment on the coverage and deformation of prepreg, it is found that the temperature affects both the adherence and bandwidth of prepreg. With the increase of temperature, adherence of prepreg increases first and then decreases, while the bandwidth keeps increasing with the increase of temperature and fluidity of prepreg. This proves the correctness and feasibility of the proposed method and provides a theoretical basis for parameters of ATL process. Finally, the influence of temperature on the placement quality of prepreg is analyzed to better the control of ATL, which provides a reference for the actual molding process.
