Abstract
Systems and methods are provided for enhancing edge breathers for composite manufacturing. One exemplary embodiment is an apparatus that includes an edge breather to facilitate manufacturing of a composite part. The edge breather includes a body, ridges disposed along a length of the body that each define an arc which is perpendicular to a lengthwise axis of the body, and openings disposed along the body that enable air to enter a hollow interior that runs along the length of the body. The arcs defined by the ridges resist compressive loads applied to the edge breather and prevent the hollow interior from collapsing under pressure applied to the edge breather by a vacuum bag during manufacturing of the composite part.
