OverviewAbout Gradel
Gradel is a Luxembourg engineering firm founded in 1965 in Steinfort and now headquartered in Ellange, with a technology centre in Hautcharage. Its Light Weight division uses robotic filament winding (the xFK in 3D process, qualified for space) and its patented GRAM (Gradel Robotic Additive Manufacturing) technology to produce ultra-lightweight carbon-fibre composite parts that are up to 60-75% lighter than metal equivalents. The company also designs mechanical ground support equipment for handling and testing satellites, serving customers such as Thales Alenia Space, Airbus Defence and Space, and OHB.
ProductsWhat Gradel builds
GRAM (Gradel Robotic Additive Manufacturing)
Patented endless-filament wet-winding technology that combines all fibre types (carbon, mineral, renewable) with any resin matrix to build ultralight 3D structures for aerospace, space, drones, and automotive.
xFK in 3D
Endless-fibre displacement/winding process, originally developed by AMC GmbH for automotive, which Gradel qualified for the space sector to produce optimised 3D carbon-fibre-reinforced-polymer meshes.
Satellite ground support equipment (MGSE)
Mechanical ground equipment for handling and testing satellites weighing several tonnes.
