A versatile option for automotive repairs or hobby projects requiring a lightweight, strong composite.
Krbnk 10FT Carbon Fiber Repair Kit

This kit provides 10 feet of carbon fiber cloth (12″ wide) along with the same epoxy resin kit components as the 5-foot version. It emphasizes high strength, low density, and corrosion resistance. The 2:1 mix ratio is maintained, with UV protection ensuring a long-lasting repair. Ideal for larger patches or structural repairs on automotive or marine parts requiring a lightweight reinforcement.
Krbnk 6.6FT 3K Carbon Fiber Repair Kit

Includes 6.6 feet of 12″ wide carbon fabric with 240 g/m², plus 8 oz resin and 4 oz hardener. The kit maintains a 2:1 resin-to-hardener ratio and UV protection for durable results. The larger cloth length enables more extensive repairs or fabricating reinforced panels with a glossy finish after curing, suitable for automotive or aero projects.
12″ x 5FT Twill Weave Carbon Fiber Resin Kit (Venom Carbon)

Twll weave fabric at 12″ by 5 feet paired with UV-stabilized epoxy resin. This kit focuses on ease of wetting out and achieving a clean, finished look. The UV-stabilized resin adds outdoor durability, making it a practical choice for exterior automotive or marine repairs where exposure to sun is a concern.
TRUE COMPOSITES Carbon Fiber Sheet & Epoxy Resin Kit

This kit combines a 36″ x 6″ carbon fiber sheet with 8 oz epoxy resin. The 2×2 twill weave provides high strength while remaining lightweight. Included waterproof epoxy resin supports durable bonding and repair applications across various substrates, including carbon fiber and composite laminates. The package is designed for straightforward installation and a sturdy finish.
Buying Guide
Key purchase considerations help ensure you choose a resin kit that matches your project needs:
- Fabric type and weave: Twill weaves offer balanced strength and flexibility, while plain weave variants may be easier to wet out for beginners. Select a fabric width and length that matches the repair area.
- Resin system and cure: Epoxy resins with UV stabilization provide outdoor durability and strong bonds. Check pot life and cure time to fit your workflow.
- Hardener ratios: A 2:1 resin-to-hardener ratio is common; ensure you can mix accurately and measure with included cups or compatible tools.
- UV and temperature resistance: For exterior use, UV stabilization and high-temperature tolerance reduce yellowing and degradation over time.
- Compatibility with substrates: Carbon fiber sticks well to most composites, metals, and wood when properly prepared. Consider surface prep steps like sanding or priming.
- Kit contents: Some kits include gloves, mixing sticks, and cups—evaluate if you need these extras to complete the project.
- Kit size and scalability: For large repairs, choose longer cloth lengths or larger sheets. For small fixes, smaller kits are more economical.
- Finish and aesthetics: If a glossy or smooth finish is desired, follow cure conditions and post-cure options to maximize sheen and rigidity.
Overall, these resin kits provide reliable options for bonding, repairing, and reinforcing carbon fiber components. When selecting, prioritize the size of the repair area, environmental exposure, and whether you need additional tools or UV protection to ensure a durable result.
