Step 1: Step 1: Safety

Most of the materials used can be harmful, resins can be a bit aggressive on the lungs and skin, be sure you work in a proper environment that is well ventilated and clean. Use gloves to work with those resins and a respiration mask. The mask is not only for the smell but as well for the toxic gasses that can access your lungs. The mask is as well good for small dust while sanding. A paper-mask (like the doctors use, is good for the dust but is not good for the gasses coming out of the resin.
That said, lets start the tutorial.

Step 2: Step 2: analyzing the broken part

Remove any loose parts on the broken part. You can do this by using a knife or something sharp to feel where you can remove some loose chips of resin/Carbon fiber. By having a clean and firm part to repair the layers of the repair will have a better bond on the broken part.
