Seamless Carbon Fiber Tubing
Seamless carbon fiber tubing for flawless surface integrity and uniform strength. Used in fluid transfer systems, robotics, and luxury automotive interiors.
Description
High-Temperature Carbon-Carbon Composite Tubes
Extreme Environment Performance Designed for scramjet combustors and hypersonic vehicle skins, our C/C composite tubes maintain structural integrity at 2,200°C in oxidizing atmospheres. The unique 4D braided architecture combines:
PAN-based carbon fibers (M40JB grade)
Pyrolytic carbon matrix (0.8g/cm³ density)
Zirconium diboride oxidation inhibitors
Ablation Resistance Comparison
| Condition | Our C/C | Standard Graphite |
