Abstract
A method of removing a vacuum bag from a composite mold. Removable strips are placed around the perimeter of the component parts and across the parts to create natural break points in the consumable materials used during manufacture of a composite product, e.g. wind turbine blade. The vacuum bag, and other consumable layers, are placed over the removable strip such that when the strips are pulled, the strip tears, in a controlled and complete manner, through each layer of consumables. This eliminates the need to use a knife/scissor to remove the finished product, thereby avoiding risk of injury.
