Your Leading Carbon Fiber Oval Tube Manufacturer
Oval carbon fiber tubes offer excellent properties such as lightweight, high modulus, and corrosion resistance. Their unique cross-sectional shape is not only aesthetically pleasing but also addresses specific challenges in high-end engineering applications where round or square tubes cannot simultaneously meet certain requirements
—solving issues related to directional stress and fluid dynamics.
We can design the layup according to your requirements, using 0.006″ and 0.008″ thickness UD prepreg. The innermost layer is oriented at 0° to enhance tensile strength, +/-45° layers increase torsional resistance, and 90° layers improve hoop strength for better resistance to external and internal pressure.
Features and Applications for Carbon Fiber Oval Tubing
Compared to round carbon fiber tubes, elliptical carbon fiber tubes offer better stability and can withstand greater torsional forces, providing unique advantages in practical applications. Production using a roll-to-roll process results in lower mold costs and unit prices, while increasing production efficiency. The UD OPP finish, with its resin-retained surface, prevents carbon fiber fraying and maintains a glossy finish, reducing the need for sanding and painting processes and further lowering costs.

Fishing Rods HandleDirectional Bending Stiffness
Applying the CFRP oval tube to high-performance fishing rods, offers two benefits: prevents accidental slippage and allows the rod to bend easily in one plane while remaining rigid in another.
