Abstract: A device for laying up a dry preform having an elongated shape includes a punch that reproduces the elongated shape of the dry preform, a depositing assembly, and a mobile carrier that moves at least one of the punch and the depositing assembly. The depositing assembly deposits, onto the punch, a fibrous band including a small amount of binding agent to make up the dry preform having a cross-section with at least two non-coplanar wings. The depositing assembly also includes pressing devices that press the fibrous band, a channel that pre-shapes the fibrous band to have the cross-section, and a calibration device that applies a normal pressure to all surfaces of the dry preform that are opposite from the punch while cooling the pressed portion of the fibrous band to control a thickness of the dry preform having the cross-section.

Abstract: The invention relates to a device and a method for the realization of elongated textile preforms intended for manufacturing load-bearing composite members by means of a method using resin infusion. More specifically, the device and the method, which are the subjects of the invention, are designed for manufacturing substantially circular preforms, intended, for example, for the realization of aircraft fuselage frames or segments of frames. The invention provides a method for depositing gradually and continuously a fibrous tape comprising a small amount of binding agent over the length of an elongated shape to make a preform whose shape comprises at least two non-coplanar wings.
