High-Performance Pultruded Carbon Fiber Tube

Our carbon fiber rods are continuous profiles manufactured using advanced pultrusion technology, perfectly combining thousands of carbon fiber filaments with high-performance epoxy resin, with the fiber orientation aligned with the rod's axis. This design gives them unparalleled specific strength (strength to weight ratio) and specific stiffness in the direction of stress.

Simply put, while maintaining strength comparable to or even higher than steel, the weight is reduced by more than 70%. It is an ideal alternative to traditional metals (such as steel and aluminum) and fiberglass materials, bringing disruptive performance improvements to your new products.

Product Advantages of Our Solid Carbon Fiber Rods

1. Extremely Lightweight

The density of our pultruded carbon rod is only 1.5-1.6 g/cm³, 50% lighter than aluminum and 70% lighter than steel. Significantly reduces equipment weight, improving energy efficiency, operating speed, and portability.

2. Exceptionally High Strength and Stiffness

Possesses extremely high tensile strength and modulus of elasticity. Performs exceptionally well in structures requiring resistance to bending and deformation, ensuring equipment stability and precision. The pultrusion process ensures that every solid carbon fiber rod has minimal elongation under load and excellent resistance to deformation, even under high stress.

3. Excellent Fatigue Resistance and Durability

Unlike metals, carbon fiber possesses excellent fatigue resistance, resisting permanent deformation or fracture under repeated loads. Furthermore, our carbon fiber rods, produced using a pultrusion process, are rust-free, corrosion-resistant, and resistant to moisture, chemicals, and harsh environments. Maintenance-free, it is particularly suitable for outdoor, medical, and chemical equipment applications.

4. Low Coefficient of Thermal Expansion

It expands almost nothing when heated and contracts almost nothing when cooled, maintaining extremely high dimensional stability in environments with drastic temperature changes, making it an ideal material for precision instruments.

5. X-ray Transmittance

It is virtually transparent to X-rays, making it a perfect material for medical equipment (such as CT scanner supports), aerospace inspection tools, and other fields.
