3. Product Features of Carbon Fiber Tube
- Ultra-high carbon content up to 95%, with extremely low ash content of only 0.03%, which eliminates impurity interference and delivers stable chemical corrosion resistance.
- Outstanding mechanical performance: tensile strength reaches 4.41 GPa and elastic modulus hits 250 GPa, featuring high rigidity and lightweight characteristics. The 1.8% elongation at break balances strength and toughness to avoid brittle fracture.
- Consistent fiber quality: uniform sizing agent content and controlled linear density deviation ensure stable composite forming performance during tube winding and molding processes. No fiber lump or adhesion issues guarantee smooth lamination and uniform wall thickness of finished tubes.
- Low overall density at 1.79 g/cm³, significantly lighter than metal pipes while retaining superior load-bearing capacity, ideal for weight-reduction projects.
- Made of 3K large tow carbon fiber raw material, which improves production efficiency for large-diameter and long-length carbon fiber tubes and reduces manufacturing costs.
4. Main Application Fields
- New energy industry: wind turbine carbon fiber tubes, battery structural support tubes
- Automotive lightweight: automotive chassis connecting tubes, new energy vehicle frame tubes
- Aerospace & unmanned equipment: drone support pipes, aerospace structural load tubes
- Sports equipment: bicycle frame tubes, fishing rod blanks, high-performance golf shaft tubes
- Industrial equipment: robotic arm lightweight tubes, pressure-resistant anti-corrosion fluid delivery pipes
5. Quality Assurance
All raw carbon fiber materials are fully inspected and issued with official quality certificates. Each batch of raw fiber records complete sampling, testing and filing information (Record No. GSHSH-R-ZG-ZL-042-2020). Our carbon fiber tubes inherit the stable quality of original carbon fiber raw materials, with full traceability of batch test data to support third-party quality verification for export and industrial procurement.
