The subject of this study is to understand the continuous impregnation process of carbon fiber reinforced thermoplastic (CFRTP) sheet using fixed rollers double belt press (DBP). Fixed rollers DBP has a complicated mechanism of pressure process. The pressure changes along the belt move under the rollers. In this study, theoretical impregnation model was developed about carbon fiber woven fabric / PA6 films materials with heat and cool process. The permeability of this material was calculated by comparing to the experimental result. Then, this model was applied to DBP impregnation process. In order to understand DBP process, material temperature profile and applied pressure profile was measured during the process. And based on these results, theoretical DBP impregnation model was developed. This model was evaluated with the experimental result and showed a certain level of validity. These understanding and the impregnation model is helpful to optimize the DBP process and to improve the machine capability for CFRTP sheet production.
