Description
The High-strength Carbon Fiber Coil Tube by QINI is a top-tier structural component engineered with high-purity carbon fiber as the core material, combining exceptional mechanical performance and versatility. Designed to meet the demanding requirements of industrial and high-tech fields, this coil tube boasts a maximum production size of 8000*800mm, with two optional surface finishes—Matte and Glossy—to adapt to different usage environments. What sets it apart is its perfect balance of high-strength, lightweight properties, and stable structural integrity, making it a preferred choice for scenarios where weight reduction and durability are critical. Whether used in aerospace engineering or sporting equipment manufacturing, this carbon fiber coil tube delivers reliable performance that outperforms traditional metal or plastic alternatives.
Process Caracteristics
The production of the High-strength Carbon Fiber Coil Tube starts with strict mandrel preparation. The metal mandrel, a key component in the rolling process, must meet ultra-high precision standards. Its outer diameter is precisely calibrated to match the inner diameter of the final product, ensuring the coil tube’s dimensional accuracy. Any deviation in the mandrel’s size would directly affect the tube’s fit and performance, so QINI implements rigorous quality checks at this stage to eliminate defects.
Next comes the core step—precise layering design of carbon fiber prepreg. The tube is crafted by winding twill or unidirectional carbon fiber prepreg layer by layer around the metal mandrel. The layering scheme is scientifically optimized: fibers in woven prepreg are oriented along the 0° axis (parallel to the tube’s length) and 90° axis (circling the tube’s circumference). The 90° orientation adds critical hoop strength, making the tube resistant to extrusion and bursting, while the 0° unidirectional prepreg significantly improves longitudinal stiffness, ensuring the tube maintains shape under tensile forces. The number and thickness of prepreg layers are tailored to meet specific outer diameter requirements, balancing performance and weight.
After winding, the assembly undergoes high-temperature curing to solidify the structure. This process not only bonds the prepreg layers firmly but also ensures stable resin content in the carbon fiber tube. Unlike traditional curing methods that suffer from uneven temperature distribution, QINI’s advanced curing technology minimizes internal stress, eliminating cracks or structural weaknesses. The result is a coil tube with consistent performance across its entire length.
Application Area
In the aerospace industry, the High-strength Carbon Fiber Coil Tube is widely used as structural components such as aircraft fuselage frames, wing stiffeners, and trusses. By replacing heavy metal parts, it significantly reduces aircraft weight while maintaining or even enhancing structural strength—directly improving fuel efficiency and extending flight range. Its resistance to extreme temperatures and corrosion also makes it suitable for harsh aerospace environments.
For ship manufacturing, this carbon fiber coil tube is utilized in hull structures, masts, and sail frames. Its lightweight property reduces the ship’s overall displacement, allowing for faster sailing speeds and lower fuel consumption. Additionally, carbon fiber’s inherent corrosion resistance eliminates the need for frequent anti-rust maintenance, reducing long-term operational costs for shipowners.
In the sporting equipment sector, the coil tube is transformed into bicycle frames, fishing rods, and ski poles. Its combination of light weight and high strength reduces fatigue for athletes during long-term use while enhancing equipment responsiveness. For example, a carbon fiber bicycle frame absorbs road vibrations better, while a carbon fiber fishing rod offers superior flexibility and sensitivity to detect bites.
