Thermoplastic polymer based carbon fiber composites have received great attentions as a lightweight structural material due to the superior advantages over the thermoset based ones in recyclability, cost effectiveness as well as good mechanical properties including impact resistance. Thermoplastic resin transfer molding using ε-caprolactam monomer, as a promising reactive process for mass-production of carbon fiber reinforced polyamide 6 composites, has some difficulties to be successfully applied to industries. In this talk, several examples on additional function materials introduced into the ε-caprolactam monomer are presented to improve the critical problems in the thermoplastic resin transfer molding such as flow instability, moisture induced termination of polymerization and degradation of property. It is expected to help the thermoplastic composite manufacturing process being successfully launched for industrial applications. |
