Περιγραφή προϊόντων

Strong, Corrosion Resistant, High Strength Pultruded Carbon Fiber Tube – Durable & Lightweight

The Pultruded Carbon Fiber Tube is a precision-engineered structural tube designed for applications requiring maximum strength, rigidity, and lightweight performance. Unlike conventional composite tubes, pultruded tubes are manufactured via a continuous process that aligns fibers along the tube axis, resulting in exceptional longitudinal strength and consistent mechanical properties.

Pultrusion is a continuous fiber-reinforced composite manufacturing process where carbon fiber rovings are pulled through a resin bath and then a heated die. The fibers are perfectly aligned along the tube’s length, producing a dense, void-free, and uniform tube with high repeatability. This ensures:

• Consistent outer diameter and wall thickness
• Optimized axial fiber orientation for maximum longitudinal strength
• Low coefficient of thermal expansion
• Smooth surface finish suitable for both structural and cosmetic applications

Mechanical Performance

1. High Tensile Strength: Exceptional resistance to axial loads
2. Axial & Bending Stiffness: Maintains shape under torsion, bending, or compression
3. Fatigue & Impact Resistance: Designed for repeated stress cycles and shock absorption
4. Vibration Damping: Reduces resonant vibration compared to metal tubing
5. Corrosion & Chemical Resistance: Resists moisture, fuels, oils, and industrial chemicals

Thermal & Environmental Performance

• Temperature Stability: Maintains mechanical properties in varying environmental conditions
• UV-Protected Surface: Optional coatings for outdoor or harsh environment use
• Long-Term Durability: Minimal maintenance required over extended service life

Surface Finish & Customization Options

• Finishes: Glossy, matte, or semi-gloss for functional or aesthetic purposes
• Fiber Types: 3K, 6K, 12K woven, or unidirectional carbon fiber
• Resin Systems: Standard epoxy, high-temperature epoxy, flame-retardant epoxy
• Dimensions: Fully customizable outer diameter, wall thickness, and length

Pultruded carbon fiber tubes can be accurately cut, drilled, machined, or bonded using proper carbide or diamond tooling. The continuous fiber alignment ensures predictable load-bearing performance even after fabrication, making them ideal for high-precision applications.

Typical Applications

• Aerospace structural frames, UAVs, and drone airframes
• Automotive lightweight chassis, suspension, and drive components
• Industrial machinery, robotics arms, and automation systems
• Marine structures, masts, and lightweight poles
• Sports equipment, performance gear, and custom engineering projects

Advantages

• Lightweight with unmatched axial and longitudinal strength
• Consistent, repeatable quality from the pultrusion process
• High stiffness, durability, and long-term performance
• Excellent corrosion, chemical, and environmental resistance
• Ideal for replacing aluminum, steel, or other metals in weight-sensitive applications

The Pultruded Carbon Fiber Tube is engineered for precision, high-strength performance, and reliability. Its continuous fiber alignment, uniform cross-section, and advanced resin system make it the preferred choice for industrial, aerospace, automotive, and high-performance engineering applications, where weight savings and structural integrity are critical.
