Abstract: Fixed rollers double belt press is an effective solution for the mass production of stampable thick organo-sheet. This system enables the continuous impregnation of multi-layers of carbon fiber fabrics with molten thermoplastic under the multiple rollers. For example, we can produce 6-mm thick organo-sheet continuously using 28 layers of carbon fiber fabrics and polyamide 6 resin films. The key point of this system is the optimization of process parameters such as belt speed, heating temperature and steel belt gaps. However, the impregnation mechanism under rollers is complicated compared to a hydraulic press system. Both impregnation of fabric and in-plane resin flow occurs with the change of pressure under rollers. In this study, this mechanism was investigated theoretically and experimentally under different process conditions and the prediction model was developed. The results will be applied to guide the optimization of the manufacturing process.
