Layer epoxy → CF → epoxy → CF … etc. → epoxy → peel ply fabric.
With a disposable brush, paint a layer of epoxy onto the surface of the mold.
Place the CF piece.
Paint a layer of resin on top of the CF piece.
Make sure to do shorter brush strokes + more stippling rather than long strokes. Long strokes increases the risk of the CF strands getting caught in the brush. The goal is to push resin into the CF and long stroke won’t help achieve this.
Squeegee out excess resin.
Repeat steps 2-4 per each layer.
After all the layers are done, place the peel ply fabric on top of the final layer.
Press the peel ply fabric to make sure that it absorbs excess resin from the final layer. You can use a squeegee to make sure the peel ply adheres to the final layer.
After the resin has cured, you can tear the peel ply off (it should come off pretty nicely). Use a scrapper or a blade to release the wet layup from the mold.
General rule is weight of carbon fiber == weight of epoxy resin solution. Do not forget to tare (or subtract) the weight of the cup that holds the resin.
