Hydrogen pressure vessels made from fiber-reinforced plastics
Lightweight pressure vessels are used to store gaseous hydrogen in the energy sector or in the automotive industry. The Fraunhofer IPT automates systems and processes for processing glass and carbon fiber reinforced plastics using laser-assisted tape winding. Due to their mechanical properties, these materials are particularly suitable for the production of lightweight, stable and corrosion-resistant components. For production, the Fraunhofer IPT relies on digital methods for the acquisition and utilization of production data as well as virtual process modeling for large-scale production.
We have developed systems for the automated production of rotationally symmetrical components such as hydrogen pressure tanks. In addition to conventional processes, an in-situ consolidation of thermoplastic tapes allows the production of pressure tanks with alternative matrix materials. In this way, tanks with different winding geometries can be manufactured. In addition, there is no need for subsequent curing. With this production process, pressure tanks can be manufactured for different industries and applications: from the storage of hydrogen as an energy carrier to compressed air storage for use in commercial vehicles.
