Satellite Structural Lightweighting

Structural mass reduction and volume optimization of commercial satellites through carbon-fiber composites, generative lattice additive manufacturing, and ultra-low-density polymer aerogels. Minimizing structural dry mass directly reduces launch costs while maximizing orbital delta-V, onboard propellant, and flat-packed constellation stack density. Key engineering adopters include SpaceX Starlink, NASA Glenn Research Center, Kerberos Engineering, and Rock West Composites.

Key technical architectures and manufacturing innovations include:

• Beryllium & Al-Be Additive Manufacturing and Precision Optics: High-precision additive and powder metallurgy processing of pure beryllium and aluminum-beryllium alloys (AlBeMet AM162/AM140, Beralcast) delivering extreme specific stiffness and cryogenic dimensional stability for aerospace structures and space telescope optics, requiring strict containment against Chronic Beryllium Disease (CBD) toxicity.
• DiskSat: 1 m diameter × 2.5 cm plate-shaped smallsat. Aluminum honeycomb core with carbon-fiber face sheets; stacks in a dispenser as a CubeSat alternative with more area/power at low structural mass.
• Atomic-6 Light Wing: All-composite redeployable solar array (Space Mast, Space Hinge, Light Sheet substrates). Vendor: up to 200 W/kg and >4× power per kg vs existing arrays.
• Apex Comet: Flat-pack satellite bus: >5 kW continuous payload power, stacks in a 5 m fairing for constellation packing.
• Thales Alenia Space AM satellite brackets: Powder-bed 3D-printed aluminum and titanium reaction-wheel and ADPM antenna brackets. TAS: reaction-wheel bracket ~30% lighter and ~10% cheaper.
• FibreCoat–Lofith space TPC panels: Aluminium-coated-fiber thermoplastic composite satellite panels. Lofith vendor claim: up to 50% lighter and 30% stronger than aluminum.
