Gurit SE 70 prepeg first to be cured in stratosphere

Both projects demonstrate that uncured prepreg can be prepared in terrestrial conditions and transported into space, for on-site curing. These results pave the way for further research into the exciting future of space construction.

About SE 70 epoxy prepreg

Gurit’s SE 70 is a hot melt, low temperature cure, epoxy prepreg system. It has been developed for use in the construction of large components using low energy cure cycles.

Excellent mechanical and toughness properties and can be achieved with a processing temperature of just 70°C / 160°F for 16 hours, enabling the use of lower cost tooling and ovens. SE 70 is widely used in sandwich structures with honeycomb, foam and balsa cores, primarily with the toughened SA 70 Adhesive Film.
