  Abstract

This study aims to optimize the polymerization conditions in a thermoplastic-resin transfer molding (T-RTM) process for the mechanical properties of carbon fiber-reinforced PA6 composites (CFPA6) using a response surface method. For this, a T-RTM process was first established with carbon fiber and caprolactam (PA6 monomer) as the base materials. Next, the injection speed, C20 (activator) rate, and C10 (catalyst) rate were selected as design variables that affect the mechanical properties of the CFPA6 composites. Experimental conditions for the three design variables were established using the central composite design (CCD) from the design of experiments (DOE) method. The significance of the CCD was verified by analysis of variance (ANOVA) and sensitivity analysis. Finally, an optimization problem was solved with an objective function of tensile strength and a constraint of the polymer conversion rate to identify the optimal CFPA6 polymerization reaction conditions.
