T-RTM is the most likely process for mass production of carbon fiber reinforced thermoplastic polymer (CFRTP) composites, applicable for automotive application. T-RTM process using the anionic polymerization of ε–caprolactam has advantages on fast curing speed, good impregnation, impact resistance and recyclability. Only two parameters that can be controlled in the T-RTM process are the resin temperature and the mold temperature (curing temperature) before and after the mixing the activator, catalyst and caprolactam. In this study, the anionic polymerization process of ε–caprolactam was investigated to optimize the T-RTM fabrication process with respect to the process temperatures. The curing process of the T-RTM (polymerization and the crystallization of the ε–caprolactam) was analyzed by cure monitoring using dielectrometry. The mechanical properties and impregnation quality of the polyamide 6 and CFRTP were measured with respect to the process temperatures. |
