A new polyurethane resin system has been developed retaining low viscosity for a sustained period before undergoing a rapid ?snap-cure?. This unique rheological behavior enabling fast injection rates for high-speed production has been captured by modeling work and integrated in PAM-RTM an industrial simulation tool allowing non-isothermal filling and curing simulations. The use of optical fibers to measure both thermal strains during processing and residual strains after manufacturing gives a good opportunity to validate simulation results.
