제품 설명

High Stiffness Round Shaped 100% 3K Roll Wrapped Carbon Fiber Tube

High stiffness carbon fiber tubes are engineered for applications that demand exceptional rigidity, low weight, and superior mechanical performance. Made from premium unidirectional (UD) and woven carbon fiber prepreg, these tubes offer outstanding stiffness-to-weight ratios—significantly surpassing metals such as aluminum and steel—while maintaining excellent dimensional stability and durability.

Our roll-wrapped carbon fiber tubes are manufactured by wrapping multiple layers of 3k twill/plain carbon fiber prepregs around a metal mold and then cured at high temperature. The UD prepregs are used in core layers, whereas the Twill/Plain is on the surface. Based on your requirement, we can also use Kevlar and glass fiber.

A high-stiffness carbon fiber tube is designed with a specialized fiber layup structure, typically incorporating a high percentage of 0° unidirectional fibers, which maximizes axial stiffness and bending resistance. These tubes maintain rigidity even under heavy loads, making them ideal for precision engineering use.

Key Features

• Extremely high stiffness-to-weight ratio
• Excellent bending and torsional rigidity
• Lightweight yet structurally strong
• Low thermal expansion for stable performance
• Corrosion, fatigue, and impact-resistant
• Smooth 3K twill/plain or UD surface finish
• Precision tolerances for engineering applications
