The carbon fiber-reinforced plastic (CFRP) is a promising material for aerospace and automotive industries as a high-strength material having desired light-weight. Especially there are tremendous interests towards thermoplastic CFRP because it can be welded or recycled upon melting, and be manufactured faster than existing thermoset CFRP. However, it is hard to be manufactured using existing resin transfer molding (RTM) process, owing to the high viscosity of polymer melts. So reactive processing has been suggested for the thermoplastic CFRP, where the low viscosity monomer melts instead of polymer melts are injected into the mold, and following in-situ polymerization enables to produce the thermoplastic CFRP. Recently we developed the high-speed reactive processing system for carbon fiber-reinforced thermoplastic polyamide-6 composite using an anionic ring-opening polymerization of ε-caprolactam. Properties of the produced CFRP will be discussed. |
