uxcell Carbon Fiber Tube 4mm OD x 2mm ID 420mm Pultruded Rod

Description

Product Overview

Experience the strength of aerospace‑grade carbon fiber in a compact, easy‑to‑install tube. This uxcell pultruded tube measures 4mm outside diameter, 2mm inside diameter and 420mm in length. The pultrusion process aligns all fibers in one direction, giving the tube superior tensile strength compared to woven alternatives. Weighing just 3.84 ounces, it provides metal‑like rigidity at one‑fifth the weight, and its smooth surface resists corrosion and heat.

Usage

Designed for high‑performance hobbyists, the tube is perfect for racing drone frames, RC helicopter wing spars, RC airplane fuselages and sailboat mast sections. Its lightweight nature improves flight efficiency, while the high modulus carbon fiber maintains structural integrity under stress. Whether you are building a custom drone or reinforcing a model aircraft, this tube delivers reliable performance.

FAQ

What is the difference between pultruded and woven carbon tubes?

Pultruded tubes have fibers aligned in a single direction, giving higher tensile strength and stiffness, while woven tubes have fibers interlaced, which can be less stiff under tension.

Can this tube be painted or coated?

Yes, the smooth surface accepts most paints and clear coats. We recommend a light‑scrape primer for best adhesion.

Is the tube compatible with standard RC drone motor mounts?

The 4mm outer diameter matches common motor mount brackets used in racing drones, making installation straightforward.

How does temperature affect the tube?

The high‑modulus carbon fiber retains its strength up to 150 °C, making it suitable for high‑performance applications.

What warranty does uxcell provide?

All uxcell carbon fiber tubes come with a one‑year limited warranty covering material defects.
