In the joint research project HyMon, researchers from the Fraunhofer Institute for Structural Durability and System Reliability LBF are working with partners to develop a sensor-based on-board structural monitoring system that will enable continuous surveillance of the H2 pressure tanks, thereby ensuring a high level of safety for hydrogen vehicles. The research work focuses on acoustic emission sensors. If a single carbon fiber tears in the pressure tank, a sound wave is generated that travels through the fibers. The sensors detect this high-frequency sound wave, which allows them to determine the number of broken fibers.
