Why Choose Us

Four Core Advantages

🔬
Dual-Source Fiber
Domestic (T700/M40-grade) or imported Toray (T700S/M40J/M46J), flexible cost-performance matching with stable supply chain.
⚡
Lightweight & High Rigidity
Density ~1.55 g/cm³, ~20% weight of 316L stainless steel. Axial stiffness matches or exceeds steel with ~80% lower moment of inertia.
📐
Engineered Laminate Design
Classical Laminate Theory (CLT) ABD matrix optimization, symmetric layup eliminates coupling. First-ply failure index FI<0.35, safety margin >2.8.
🛡️
Multiple Surface Options
Hard chrome, SUS sleeve+chrome, nano-ceramic, conductive wear coating, rubber covering, WC HVOF — from high wear to anti-static.
