Product Description
These 3/8 inch carbon fiber rods are manufactured by pultrusion for projects requiring high stiffness and low weight.
Our 3/8″ (nominal 9.5mm) carbon fiber rods are solid round pultruded bars with unidirectional fibers in a resin matrix. They provide high stiffness and low weight, do not rust or corrode, and are suitable for drones, RC models, structural reinforcement, and DIY projects. The matte black finish is typical for pultruded carbon fiber rods.

Frequently Asked Questions
How do I cut a 3/8″ carbon fiber rod at home?
You can use a rotary tool with a cutting wheel, a fine-tooth hacksaw, or an abrasive cutting wheel. Always wear a dust mask and safety glasses. For cleaner cuts, wrap masking tape around the area you’ll be cutting to reduce fraying.
Will a 3/8″ carbon fiber rod bend?
These rods are designed to be stiff and won’t bend much under normal use. If your project needs flexibility, carbon fiber might not be the right choice. The rod will break rather than permanently bend if too much force is applied.
How much weight can a 3/8″ carbon fiber rod support?
The exact weight depends on how you’re using it. When supported at both ends, a 3/8″ carbon fiber rod can handle significant weight, especially compared to its own lightweight nature. For specific load-bearing projects, it’s best to test your setup before finalizing the design.
Can I paint a carbon fiber rod?
Yes, you can paint carbon fiber rods, but you’ll need to prepare the surface first. Lightly sand the surface, clean it thoroughly, and use a primer designed for plastics before applying your chosen paint. Remember that paint will add a small amount of weight.
Are carbon fiber rods waterproof?
Yes, carbon fiber rods are naturally resistant to water and won’t rust or deteriorate when wet. This makes them excellent for outdoor projects, marine applications, and anywhere moisture might be an issue.
Is it safe to handle carbon fiber rods?
Generally yes, but you should wear gloves when cutting or sanding to avoid splinters from carbon fibers. Always wear a mask when cutting to avoid inhaling carbon dust, which can irritate your lungs. After cutting, wash your hands before touching your face or eyes.
What’s the difference between 3/8″ carbon fiber rod and fiberglass rod?
Carbon fiber rods are significantly stronger and stiffer than fiberglass rods of the same size, while also being lighter. Carbon fiber rods are typically black, while fiberglass rods may be various colors. Carbon fiber is generally more expensive but offers better performance for projects where strength and weight are important.
What adhesives work best with 3/8″ carbon fiber rods?
Epoxy adhesives designed for composites work best. Two-part epoxies create strong bonds, especially if you lightly sand the surface of the rod first. For quicker projects, cyanoacrylate (super glue) can also work well, particularly with an activator spray.
