Professional Carbon Fibre Repair for the Home Mechanic
A cracked frame doesn’t have to mean a costly replacement. The AMT Composites Carbon Fibre Bicycle Repair Kit is engineered to provide cyclists and mechanics with the exact tools needed to perform structural repairs on carbon fibre frames. Whether you are dealing with a minor hairline fracture or a more significant crack, this kit offers a guided, step-by-step approach to restoring your bike’s integrity.
Dual-Layer Reinforcement Technology
Safety and strength are paramount in bicycle repair. This kit utilises a proven two-stage reinforcement process:
- Uni-directional (UD) Carbon: Used for the primary repair to span the crack and provide targeted longitudinal strength.
- Twill Weave Carbon: An epoxy-coated outer layer that wraps the repair for multi-axial strength and a classic “carbon fibre” aesthetic.
High-Performance Epoxy System
At the heart of the kit is the Biresin CR122 Epoxy Resin. Designed for composite laminating, this resin ensures deep penetration into the carbon tows and the frame’s existing structure. When followed by an elevated post-cure at 60°C, the repair reaches maximum structural strength, ensuring your frame is ready for the road or trail.
Comprehensive Kit Contents
We’ve included every consumable you need to get the job done right the first time:
- Carbon Fabrics: 200 x 250mm UD Carbon
- 500 x 200mm Twill Weave Fabric.
- Resin System: 250g Epoxy Resin (Biresin CR122) and 75g Hardener.
- Application Tools: 2 x 25mm Laminating brushes, 10 x tongue depressors, and 5 x 250ml mixing cups.
- Precision Measurement: 60ml and 20ml syringes to ensure the perfect 100:37 mixing ratio.
- Finishing Supplies: 120 and 220 grit waterpaper for sanding, plus a roll of insulation tape for compression.
- Safety: 5 pairs of Nitrile gloves.
Technical Specifications
- Mixing Ratio: 100 parts resin to 37 parts hardener by volume.
- Cure Time: Minimum 16 hours at room temperature.
- Post-Cure (Recommended): 4 hours at 60°C for significantly increased strength.
- Application: Suitable for most cracked carbon fibre bicycle frames.
- Expert Tip: For the best results, use the included insulation tape to bind the wet repair tightly. This compresses the carbon layers and squeezes out excess resin, resulting in a lighter, stronger repair.
PLEASE NOTE:
Not all damaged areas are the same or in easily accessible places, so the basic information provided below is only a guide. There are many alternative methods for making the repair. Don’t be afraid to experiment and adapt the repair to suite your needs!
