Speedpreg

Development of a High-Speed Winding Process

Reducing CO2, weight and costs, but also securing our future energy supply are key drivers of innovation in many industrial sectors, such as the automotive and aircraft industries, but also in the energy industry. However, hydrogen or natural gas / biogas have a significantly lower (volume-related) energy density compared to gasoline or diesel; therefore gas storage must be under high pressures up to 700 bar. High-pressure containers subjected to internal pressure are a classic field of application for fiber reinforced polymer composites (FRPC). Weight savings – compared to steel containers (the so-called Type I container) – of up to 70% are achievable. In addition to pressure vessels, the technology to be developed in the project also addresses aerospace applications such as rocket boosters or torsion waves, and thus other interesting markets for high-quality FRPC winding parts. The central objective is to achieve significantly faster winding processes in the future by developing a completely new fiber impregnation unit with a coordinated, innovative material development. Based on the new fiber impregnation unit and the new resin system, the aim is to increase the maximum winding speed by up to 100%.

Due to the resulting higher economic efficiency of the method, the project thus contributes to a cost reduction of FRP winding components, such as high-pressure hydrogen containers, e.g. for H2 transport in H2 trailers or H2 fuel cell vehicles
