Abstract
A composite structure is prepared in a mold using a vacuum bag with an edge breather separated from a layup to be formed into a composite. A means of communication between the edge breather and the layup provides a path for air being drawn from the layup and to provide a path that closes off and prevents excess resin flow from the layup as it cures.
