Development and Application of Fiber Optical Sensors for RTM and SHM

This presentation, made by Vladislav Reimer, Scientific Project Manager at FiSens, explores the development and application of fiber optical sensors based on fiber Bragg gratings (FBG), specifically designed for Resin Transfer Molding (RTM) and Structural Health Monitoring (SHM). It highlights how these sensors enable and enhance real-time monitoring of resin flow during RTM, while also providing crucial data for assessing the structural integrity of components. The integration of fiber optical sensors aims to improve manufacturing efficiency and product qualityand increase long-term reliability in composite materials.

Integration of FBG Sensors in CFRP RTM Parts and Data Analysis for Resin Flow Monitoring

This presentation, made by Andreas Krenz, Research Scientist at Fraunhofer IFAM, introduces a real-time monitoring system for Resin Transfer Molding (RTM) using embedded Fiber Bragg Grating (FBG) sensors in carbon fiber reinforced plastic (CFRP) preforms, tailored for aerospace applications like turbine blades. These FBG sensors enable real-time tracking of resin flow and temperature, using a novel method to accurately detect and analyze the resin flow front—critical for ensuring part integrity.

Printing of Sensors on Composite Components for Aerospace Applications

This presentation, made by Ingo Wirth, Project Manager, Functional Printing at Fraunhofer IFAM, presents how the aviation industry increasingly demands Structural Health Monitoring (SHM) for carbon fiber reinforced composites (CFRP) due to their favorable stiffness-to-weight ratio. A significant challenge is integrating smart sensors into these lightweight structures without affecting their mechanical properties. This presentation introduces the use of innovative printing technologies to embed sensors directly into composite components. Specifically, piezoelectric (PZT) and temperature sensors were integrated onto aeronautical CFRP parts using screen printing and Aerosol Jet printing techniques.

Hybrid twin for online monitoring of the Resin Transfer Molding process

This presentation, made by Eric Monteiro, Associate professor at Arts et Métiers Institute of Technology, displays that the Resin Transfer Molding (RTM) process is widely used for manufacturing composite parts in aeronautic but is still not robust. One objective of the MORPHO project is to develop a strategy to optimise in real-time the RTM process. To do so, new sensors have been developed as well as new hybrid model of the process. This model combines a reduced multiphysics finite element model and a data-driven ignorance model to predict in real-time the resin flow front position.
