Composite satellite structures need to be extremely lightweight, stiff and durable: qualities traditionally achieved with materials that are difficult to repair, dismantle or recycle.
SCMM is investigating whether advanced vitrimer composites can change that equation. The demonstrator is a satellite sandwich panel combining an aluminium honeycomb core with unidirectional carbon-fibre composite skins made using a LIST-developed vitrimer resin formulated for demanding space applications. 

The demonstrator is designed to explore something conventional space composites struggle to offer: disassembly, recycling, healing and repair using patches, alongside the mechanical performance required for space applications. These are capabilities that could allow composite structures to retain more of their value rather than becoming difficult-to-process waste.

The material also passed space-specific constraints, including radiation tests. Initial material testing has delivered properties above the project specifications, while qualification work and sandwich-scale manufacturing continue. 

The broader impact is a new approach to high-performance space composites: designing not only for launch and operation, but also for repairability and recovery.
