SM@RTM. Project Description.
The Resin Transfer Molding (RTM) process offers significant advantages for manufacturing high-performance composite materials, including superior surface finish, net-shape geometries, high mechanical properties, and reduced production times and resource consumption. However, strict process control is required to ensure proper resin impregnation into the dry fiber while avoiding common defects such as dry spots, porosity, and rapid flow channels, which can affect the final component’s performance.
These control strategies largely rely on operator intervention and the data available during the process, limiting productivity to low-volume manufacturing environments. To address this, SM@RTM aims to enhance RTM process competitiveness by integrating predictive digital technologies, in-situ process monitoring, and automated control systems, providing real-time support at all production stages.
SM@RTM Implementations:
- Infrared thermography-based artificial vision systems for monitoring the manufacturing process of dry fiber preforms using Automated Fiber Placement (AFP).
- Embedded sensors within RTM molds for flow front monitoring and parameter evaluation, utilizing fiber optic sensor (FOS) technology and commercial DC sensors.
- Automated closed-loop control system for injection parameter regulation.
- Implementation of Digital Twins for both AFP preforming and RTM processes, integrated into a Human-Machine Interface (HMI) with Reduced Order Model (MOR) simulations, enabling real-time decision-making support on the shop floor.
- New automated composite mold manufacturing technologies using Fused Granulate Fabrication (FGF) for one-shot injection of 3D components.
