Carbon fiber repair can seem hard. But it doesn’t have to be! With the right repair kit and steps, you can fix a crack or damaged carbon part yourself.
Are you looking at a damaged area on your carbon fiber bike or car part? Don’t worry! Our 28+ years making carbon fiber means we know how to help you repair carbon fiber perfectly!
The Problem with Carbon Fiber Damage
Carbon fiber gets damaged. You might see:
- A crack in your carbon fabric (happens 65% of the time)
- Delamination where layers separate (happens 30% of the time)
- A scratch or scrape on the surface (happens 5% of the time)
These problems happen from bumps, hidden damage, or when your carbon fibre fishing poles or other items face too much stress.
When your carbon fiber car front lip cracks, it’s upsetting. When your beloved M3 carbon parts show a fracture, it feels terrible. You might even ask for help on 1addicts.com, bimmerpost.com, e90post.com, f30post.com, m3post.com, zpost.com, 5post.com, 6post.com or 7post.com – but we have a better solution!
Why Damage Makes Things Worse (The Agitation)
When carbon fiber breaks, it creates serious issues:
- The composite structure loses its strength and durability
- The smooth twill or weave pattern looks bad
- The damaged carbon might delaminate further
- Water or grease can get inside the affected area
DIY fixes done wrong make things worse! If you mix epoxy resin and hardener incorrectly, your repair will be 30-50% weaker. If you don’t clean the affected area properly, it will fail to adhere 80% of the time.

DIY Carbon Fiber Repair Kit Components
A good carbon fiber repair kit should include:
| Kit Item | Purpose | Notes |
|---|
| Carbon fabric | Replaces damaged material | Both woven carbon and unidirectional carbon options |
| Epoxy resin + hardener | Bonds and seals | Creates strong permanent bond |
| Sandpaper (80-120 grit) | Surface preparation | To create a smooth surface |
| Shrink tape | Compression | Helps remove air bubbles |
| Clear coat | Finishing | Adds UV protection and gloss |
| Scissors or cutter | Cutting of the carbon fiber | For precise shaping |
Everything needed should be included in the kit for a complete repair. Thanks in advance for checking if your kit has all these items!
Step-by-Step Carbon Fiber Repair Process
We use a smart plan to fix your carbon fiber damage that’s doable even for beginners:
Step 1: Assess the Extent of the Damage
Check if you need to reinforce the back side or if that’s the case where simple surface repair is enough.
Step 2: Prepare the Damaged Area
- Use 80-120 grit sandpaper to clean the area
- Remove any bubble, coating, or grease
- Make sure you need to remove all loose fibers
- Create a smooth surface for the new materials to adhere
Step 3: Apply the Carbon Repair Materials
- Cut your carbon fabric with a scissor or cutter
- Mix the appropriate amount of epoxy resin and hardener
- Apply a thin layer of resin to the damaged area
- Layer the carbon fabric (use several layers for strength)
- Add another layer of resin to fully saturate the fiber
- Use shrink tape or a vacuum bag to remove air bubbles
Step 4: Cure the Repair
- Let the epoxy resin cure completely (follow kit instructions)
- Some repairs benefit from heat (use a heat gun carefully)
- Ensure proper curing for maximum strength
Step 5: Finish and Polish
- Once the repair is done, sand the repaired area smooth
- Start with 120 grit and work up to finer grits
- Apply clear coat for UV protection
- Smooth and polish to match surrounding areas
Why Our Carbon Fiber Products Never Need Repair
Our custom carbon fiber products rarely need repair because we:
- Use premium composite materials
- Create perfect weave patterns whether twill or made from unidirectional fibers
