I method of manufacturing shaped stringers? T? which reduces the effect of Mexican hat curing tool used therein # Method of manufacturing shaped stringers "T" to a plane in which the stringers have a core and a foot, the method comprising:. a first step of forming a laminate of hot carbon fiber geometry for semi-stringers shaped cross section of? L ?, a second step of placing together the two half-shaped stringers? L? hot formed to form a shaped stringer? T ?, a third stage of the coencolar shaped stringer? T? resulting in a cured surface with an adhesive line between them and a fourth step of curing the shaped stringer? T? obtained within a vacuum bag using angular invar alloy as curing tools. The method is characterized in that the angle of invar alloy used are produced without any slots in the top for retaining profile.
