Halcyon & space: expertise for lightness
Reaching Further, Lighter… and More Sustainable
In the space industry, every ounce matters. To meet the growing demands for performance, reliability, and sustainability, Halcyon offers a unique structural technology: aluminum honeycomb sandwich panels—lightweight, strong, and adaptable to the most complex shapes.
Designed for launchers, satellites, and onboard equipment, our solution combines mechanical excellence with a reduced environmental impact.
A customized solution for spatial structures
Our aluminum honeycomb sandwich panels are particularly suitable for :
-
micro-launchers
-
non-load-bearing subassemblies (secondary structures)
-
les équipements embarqués et charges utiles
Thanks to their rigidity, lightness and design flexibility, our aluminum honeycomb sandwich panels can be easily integrated into a wide variety of space applications, while guaranteeing performance and reliability.
