How To Make a Successful Carbon Fibre Repair

Inspect - Prepare - Bond - Finish

Inspect

  • Identify the damage. If unsure, consult a composite repair specialist.

Prepare

  • Wear safety gear: dust mask, gloves, and other essentials to protect yourself and your workspace.
  • Ensure all surfaces are dry and clean.
  • Use emery cloth to sand through lacquer and paint until the carbon fibre is exposed, creating a keyed surface.

Bond

  • Mix Resin and Hardener in a 2:1 ratio using syringes or mixing cups to measure with more precision.
  • Prime the repair surface with a small amount of the resin mix.
  • Apply epoxy to the dry carbon fibre using a spreader to saturate the material and then remove excess. Use the box as a makeshift work surface if need be.
  • Place the epoxy-covered carbon fibre over the damaged area, overlapping by at least 30mm.
  • Wrap with Shrink Tape, ensuring overlaps (5mm minimum) and wrapping the correct way to allow easy removal i.e. Shrink tape is release coated on the outside – think the opposite to sticky tape.
    • Start by taping a leading end on the frame and move into the repair zone, finish past the end of the repair. Double up if you wish.
    • Heat with a hair dryer or heat gun to fully shrink the tape. take care not to scorch the tape. 
  • Let cure for 24 hours at room temperature or 60 minutes with heat. Fully cured epoxy is hard and non-sticky.
  • Remove the Shrink Tape.

Finish

  • Sand to smooth out high spots.
  • Apply paint or primer to protect from UV light.
  • Add the Ouch Sticker as a badge of honour (optional).

 

Health & Safety - Use a dust mask and body covering when sanding/grinding Carbon Fiber. Avoid skin contact with epoxy while it is wet. Do not grind or sand uncured epoxy. See MSDS for full information.
