Zusammenfassung:	The present invention includes methods (202b, 202c) of preparing a composite structure (200) comprising: placing a first ply (202b) of a fibrous material with a curable material on a layup tool (204); adding one or more additional plies on the first ply (202a), wherein each of the one or more additional plies (202b, 202c) has a perimeter that is different in size around the perimeter than a previous ply to form a taper; and curing the composite structure (200), wherein the curable material is selected to minimize, limit, control, or eliminate the outflow of the curable material along the perimeter of the composite structure (200) during the curing step.
