The SM@RTM project comes to an end
The SM@RTM project aimed to improve the competitiveness of RTM processes using predictive digital technologies, in-situ process monitoring and automated control systems, providing plant support in all phases of production using artificial vision systems with thermal cameras to monitor automated preforming processes, fibre optic-based embedded sensors in moulds for monitoring RTM process parameters, implementation of a closed-loop control system based on electro-valves, implementation of an HMI system with integration of reduced order models (ROM) for process parameter evaluation, and implementation of new resin injection moulding technologies using large-format additive manufacturing.
Following the completion of the technical work packages, the proposed developments are obtained:
Integration of a thermal imaging camera into a robotic arm for the manufacture of dry fibre preforms: the thermal footprint of the material (after its temperature activation process) is used to assess the possible appearance of defects in the preform and their effect on the subsequent stages of manufacture.
Large-format smart additive manufacturing moulds: Fibre optic-based process sensors (pressure + temperature) were developed. They are integrated both into the mould structure for monitoring process temperatures and into the surface in contact with the part to measure the injection process in the RTM stage. These moulds were developed using large-format additive manufacturing (LFAM) with high-performance plastics reinforced with short carbon fibre for high pressure loads.
Closed-loop control system, integrating injection vessel and human-machine interface (HMI) with reduced-order models (ROM) for process evaluation: An industrial system was developed that integrates a pressurised resin injection vessel, an electro-actuated valve system and activation mechanisms for closed-loop control of the resin injection process, enabling flow control during the process. All the sensors and data generated in the process feed into a user interface, powered by simulation models, for process parameter evaluation and quality control in the preforming and RTM resin injection stages.
Following the latest integration tests and manufacturing at the COMPOXI facilities, the technical developments of the project have been completed, pending final evaluation and audit of the project. This last year has seen outstanding joint work by all the partners and participating entities in the completion of all the technical developments.
