| Résumé | In this study, carbon fiber/epoxy composite flat panels were fabricated by a resin transfer molding (RTM) process. A dielectric sensor was used to monitor the curing process of these panels. In the experiment, three dielectric cure monitoring tests were first conducted under isothermal conditions to correlate the dielectric ionic conductivity with the degree of cure and the glass transition temperature of the epoxy resin. Then panels were fabricated using RTM process in three different scenarios: the resin was injected at three different temperatures: 100°C, 120°C and 180°C, respectively, and then cured at 180°C for about 2 hours. The degree of cure and the glass transition temperature of the composite panels were displayed by custom-made software "Cure Watch" in real time. Based on the degree of cure and glass transition temperature obtained in the experiment, the optimization of the cure cycles was suggested. DMA measurements were conducted to verify the cure monitoring results. |
