For next civil aircraft generation, the schedule is to produce 60 aircrafts per month. Today, large size parts production with conventional processes such as autoclave curing allows the production of about 1 part per day. To fulfill 60 aircrafts per month the number of autoclave to invest will be too high to comply with global final production cost. This paper presents results on new processes development done during EFFICOMP project to reduce the cost and the manufacturing time of structural thermoset composite parts. Composite panels up to 80 plies have been cured with a new concept of resistive curing based on Joule effect in carbon fibres with a heating rate of 10°C/min. Composite thin panels with curvature representative of fuselage panels have been successfully laid-down with automated deposition of semi cured tows, and final polymerization done out of autoclave in a simple oven. The Latest results are moreover highlighted. Conclusions are drawn, which address the robustness and reliability of these new technologies, with regards to the final quality of the composite parts. |
