In-situ Structural Health Monitoring of Functional Composite Structures by Truly-Integrated Carbon Nanomaterial-Based Sensors (ISIMON)

The ISIMON project focuses on developing the next generation of smart, self-sensing fibre-reinforced polymer (FRP) vessels for high-pressure hydrogen storage. These innovative vessels are designed not only to store fuel safely but also to monitor their own structural condition throughout manufacturing and operation actively.

At the core of this technology are nanocomposite (NC)-based sensors, permanently integrated into the FRP structure during filament winding. These sensors enable real-time measurements during fabrication and continuous structural health monitoring, significantly improving safety, reliability, and performance.

To optimise vessel design, ISIMON combines advanced modelling, simulation, and machine learning. Topology optimisation reduces material consumption without compromising strength, while machine learning supports early damage detection and long-term performance assessment.

With enhanced safety features, reduced maintenance demands, and lower production costs, ISIMON has the potential to transform high-pressure hydrogen storage for the automotive, aeronautics, and aerospace industries. The result is an intelligent storage solution that supports a sustainable, efficient, and economically viable hydrogen future.

In 2024, the ISIMON project on "In-situ structural health monitoring of functional composite structures by truly integrated carbon nanomaterial-based sensors" was granted by the Saxon State Ministry for Science, Culture, and Tourism (SMWK) in Germany, VINNOVA in Sweden, and the Latvijas Zinātnes Padome (Latvian Council of Science) in Latvia.
