Step Five – Rotate mold

A motor rotates the mold to distribute the resin evenly. The bladder contains air and expands as the vacuum is created. This helps push the carbon fiber-now impregnated with resin – tightly against the inside of the mold for a clamping effect. After the carbon-fiberfuselage sets up, it is removed from the mold. Users can cut out, say, the door, and remove the bladder.
