1K 3K 12K 0.125 Hollow Carbon Fiber Tube

Product Overview

At SYCarbonFiber, we provide engineering and production services for ultra-thin hollow carbon fiber tubes with 0.125mm wall thickness, available in 1K, 3K, and 12K fiber options. These tubes are ideal for precision components in drones, robotics, CNC systems, and weight-sensitive structural assemblies.

Manufactured using T700 or T800 grade carbon fiber and aerospace-grade epoxy resin, our tubes offer superior strength-to-weight ratio, excellent rigidity, and a clean woven finish. Roundness and straightness tolerance are strictly controlled, with deviation ≤0.2mm per meter.

We support every project stage—from material selection and joint design to Finite Element Analysis for structural validation under real-world conditions.

Popular specifications are kept in stock for fast shipping within 3 to 5 business days. Custom configurations, including fiber tow size, wall thickness, weave orientation, or finish, are available within 15 to 20 days. For urgent production, we offer expedited turnaround in as little as 48 hours.

SYCarbonFiber is trusted worldwide for advanced carbon fiber tubing solutions that combine precision, performance, and durability.
