Invent GmbH develops a sensor network for active structure monitoring

The company together with six partners developed an integrated sensor-based diagnostic system, to reduce the mass of trains by using composite materials more effectively and at the same time detect material damage at an early stage.

In aerospace, as well as in the automotive industry and in the development and production of rail vehicles, lightweight construction has been an issue for decades – every weight saving reduces emissions and thus also costs when flying into space, traveling through the troposphere or even just getting to work. And whether it is a spaceship or a regional train, the demands on robustness, safety and reliability of the materials are very high and subject to strict specifications – fibre-reinforced composites also have special damage-mechanical characteristics due to their multilayer and complex structure.

But how can the condition of components in use actually be checked?
Invent GmbH from Braunschweig, together with six partners, has investigated this question with a view to rail transport and developed an integrated, sensor-based diagnostic system in the joint project faWaSiS.

Lightweight construction on rail: Invent develops a sensor network for active structure monitoring

This system can significantly reduce the mass of trains by using composite materials more effectively and at the same time detect material damage at an early stage. The key is the use of piezoceramic area transducers…
