Towards the dynamic optimisation for the cure control of thermoset–matrix composite materials
2005
Abstract In this paper, the real-time model identification and optimisation tools for the model-based control of the curing of thermoset–matrix composite materials are presented. Combining a computer simulation tool, a versatile and robust optimisation algorithm and real-time dielectric measurements, optimal cure cycles for composites production with improved quality, increased productivity and reduced scrap can be designed. With the proposed method the main characteristics of the composites production related to the cure process can be identified in real-time and in situ using the same optimisation method that will be used successively for the online optimisation of the on-going process. The applicability and the effectiveness of the proposed technique for the design and control of the cure cycle of a common aerospace epoxy resin are demonstrated.
