Product Information

Full details

The Harfington Carbon Fiber Round Rod is an ideal solution for hobbyists and engineers working on structural reinforcement projects such as RC airplanes, quadcopter helicopters, and custom model building. These rods offer an exceptional strength-to-weight ratio and superior corrosion resistance compared to traditional carbon steel or aluminum, though users should be mindful that they require careful cutting and handling to avoid splintering or measurement errors.

FAQs

Can I bend these rods?

No, carbon fiber rods of this diameter are designed for structural rigidity and will break if forced to bend.

What is the best way to bond these rods?

Epoxy resin is generally the strongest option, though medium-viscosity CA glue is suitable for smaller model-building tasks.

Are these rods hollow or solid?

These rods are solid carbon fiber, designed for maximum compression and bending strength.

How many pieces are included?

Each set contains 10 pieces of 8mm x 200mm rods.

Do I need to paint them?

No, they have a professional smooth finish, but you can paint them using standard model spray paints if desired.

Troubleshooting

The rod is splintering when cut.

Apply a piece of masking tape over the cutting line before sawing to help keep the fibers held in place.

The rod does not fit perfectly into a pre-drilled mount.

Use a light grade of sandpaper to reduce the diameter slightly or verify that your mount hole is exactly 8mm.

Pros and Cons

Pros

  • Significantly lighter than metallic alternatives
  • High elastic modulus for better stiffness
  • Highly resistant to environmental corrosion
  • Smooth finish suitable for professional-grade aesthetic models

Cons

  • Material can be prone to splintering if cut improperly
  • Manual measurement may vary slightly by 1-5mm
  • Requires specialized cutting tools for clean edges
  • Rigidity means it cannot be bent into shapes

Setup, Compatibility & Care

To ensure the best performance from your Harfington carbon fiber rods, proper preparation is essential:

  1. Measuring: Always verify the length against your design plan, accounting for the potential 1-5mm variance inherent in the manufacturing process.
  2. Cutting: Use a fine-tooth hacksaw or a Dremel tool with a reinforced cutoff wheel. Always wear a mask and eye protection, as carbon fiber dust is an irritant.
  3. Finishing: After cutting, lightly sand the edges with fine-grit sandpaper to prevent fraying or splintering.
  4. Bonding: For structural assembly, use high-quality epoxy or specialized CA glue (cyanoacrylate) designed for composite materials to ensure a permanent, high-strength bond.
