Carbon fiber tubing lightweight and high strength as its core advantages, combining corrosion resistance, high modulus, and low creep and fatigue resistance. Utilizing high-quality carbon fiber and resin composite molding, its specific strength far exceeds that of traditional metal tubing, while its weight is only 1/4 that of steel. Carbon fiber tubes is suitable for various applications including aerospace, drones, and sporting equipment, maintaining structural stability in complex environments. With its superior mechanical properties and durability, it has become the preferred material for lightweight upgrades in high-end equipment.
Product Features
 | Lightweight |
| With a density of only 1.5-2.0 g/cm³, approximately 20%-25% of steel and 60%-70% of aluminum alloy, it significantly reduces weight while maintaining structural strength. This makes it particularly suitable for aerospace and sports equipment (such as Carbon fiber bicycle frames and rackets), reducing energy consumption and improving operational flexibility. | |
 | Excellent Strength and Rigidity |
| Tensile strength generally exceeds 3500-4800 MPa (6-12 times that of ordinary steel), and the elastic modulus reaches over 165 GPa. It exhibits strong bending and tensile strength, can withstand high loads, and is not easily deformed, making it suitable as a high-stress structural component (such as drone frames and carbon fiber medical device support arms). | |
 | All-Environment Corrosion Resistance |
| Excellent chemical stability, resistant to harsh environments such as acids, alkalis, salt spray, and humid heat. After immersion in 5% salt water for 1000 hours, the strength loss is less than 3%. No anti-rust coating is required, and it can be maintenance-free for over 10 years in marine and chemical environments. | |
 | Flexible Customization |
| The axial/circular strength of the carbon fiber pipe can be specifically optimized by adjusting the carbon fiber laying direction (0°, ±45°, etc.), wall thickness, and cross-sectional shape (circular, square, rectangular, etc.) to suit different application scenarios and meet personalized design needs better than standardized metal pipes. | |
 | Superior Fatigue Resistance and Durability |
| Fatigue life is 5-10 times that of aluminum alloys. After 10⁶ cycles of loading, the strength retention rate exceeds 85%. In high-frequency vibration and repeated stress scenarios, its service life far surpasses that of metal pipes. | |
 | Excellent dimensional stability |
| With a low coefficient of thermal expansion (-0.5~1.0×10⁻⁶/°C), dimensional deformation is <0.1% even under alternating high and low temperature environments (-50~150℃), requiring no additional correction and maintaining precise shape to ensure long-term stable operation of the equipment. | |
 | Low energy consumption and easy processing |
| High specific strength allows for a 30%-50% reduction in pipe wall thickness for the same load-bearing requirements, increasing processing efficiency such as cutting and connecting by 40%, and eliminating metal dust pollution during processing. |
Explore the Production Process
Raw Material Preparation
High-strength carbon fiber filaments (e.g., T700/T800 grade) and epoxy resin are selected and mixed in a specific ratio to ensure fiber-resin compatibility.
Prepreg Preparation
Carbon fiber filaments are uniformly impregnated with resin using an impregnation machine, controlling the resin content at 30%-40%. After drying and curing, prepreg rolls are produced.
Tube Forming
The prepreg is wound or laid on a mandrel according to the designed layup angle. It is then rolled into shape using autoclave, pultrusion, or winding processes to ensure tight interlayer bonding.
Curing Treatment
The material is cured at 120-180℃ and 0.3-0.6MPa pressure for 1-3 hours to ensure complete resin cross-linking and the formation of a stable structure.
Post-Processing
After curing, the material is demolded, cut, polished, and chamfered, with precise control of dimensional tolerances (±0.05mm). Surface coating may be applied if necessary.
Quality Inspection
Through ultrasonic testing, tensile testing, dimensional measurement, etc., we ensure that the strength, wall thickness, straightness and other indicators meet the industry standards.
