Resin does not easily flow into the carbon fiber cloth – it needs some encouragement, usually by pressure.
- If you are making a body tube, this is most easily done using a mandrel for the form, applying the carbon fiber and resin, wrapping with a heat shrink tape and heating. Shadow Aero has an excellent video series for sale on how this is done, and plans for sale to make your own oven.
- If you are making a part from a mold, this is most easily done by vacuum bagging and heating, or using an autoclave to apply both heat and pressure. The videos below show how to make a part from a mold using a vacuum bag. Another video shows how you can make your own pre-preg material.
