DIY carbon frame repair

Wheels of Happiness

One need not worry about repairing carbon frame.  No need to bring to rush this to CNC near Sta Lucia for 4 to 6 figure repair.  You can do this yourself.

Steps:
1.   Do the coin test;   Tap the part you suspect to be broken.  If the sound changes and sound becomes dull, then it is broken.

2.  Remove other parts.   Cover the other parts of the bike, paper, masking tape to prevent epoxy from spoiling other parts of the bike.  Use safety equipment:   face mask, gloves, if needed respirator.   Carbon fiber dusts are bad for the skin and lungs.   

3.  Sand paper the broken part.

4.  Cut the carbon to fit into the broken part.

5.  Mix the epoxy.  Some say 1:1  (hardener to epoxy) some say 1 to 2.

6.  Apply epoxy with a brush (tooth or paint) to the broken part and the carbon fiber.

7.  Paste.  Apply more epoxy.  To be sure, you make this three layers.

8.  Attach compression  tape.    Secure with electrical or duct tape.

9.  Shrink the shrink tape with heat gun or hair dryer.


10.  Leave overnight.

11.  Sandpaper

12. Paint.
