Detailed Description
Mechanical engineers specifying drive shafts and pressure lines require predictable hoop strength, torsional stiffness, and fatigue life. Steel torsion bars (7.85g/cm³) add parasitic inertia to robotic joints; aluminum tubes lack torsional rigidity for torque >50N·m continuous.
Feature: T700/T800 filament wind with adjustable [hoop/axial/helix] ratio, fiber angle ±1.5°, autoclave post-cure.
Advantage: Hoop tensile ≥1800MPa, burst pressure tested per batch (hydrostatic to failure), GJ up to 45N·m² (40mm OD×3mm wall), fatigue >5M cycles @R=-1 50% UTS.
Benefit: 70% lighter than steel shaft at equivalent torsional stiffness; customizable fiber architecture to match your torque/speed envelope; we supply FEA beam properties (GJ, EA, EI) in NASTRAN/ANSYS format; hydrostatic burst test coupon per production lot; CTE tunable near-zero for precision roller applications.
End preparation: bonded metal insert, threaded adapter, or flange bonding. Full test report (FVF, burst pressure, torsion spring rate, CTE) per batch.
