Lightweight Beam Structures Using Unidirectional Carbon Fiber Fabric
— A System‑Level “Gram‑Scale Weight, Ton‑Scale Stiffness” Solution for B2B Applications
1. Market Pain Points
- Aluminum beams have reached a weight‑reduction limit—becoming too thin compromises stability.
- Steel beams are overly heavy, negatively impacting cycle times and energy consumption.
- Conventional fabric layups waste fiber and fail to deliver adequate specific stiffness.
Unidirectional (UD) Carbon Fiber Fabric features 100 % 0° fiber orientation, boosting specific stiffness by 4–7× and specific strength by 6–10×. It is the ultimate lightweight core material for beam structures.
