Abstract: A tooling pressurizes a work zone of a part made of composite material. The composite material includes a fiber reinforcement densified by a resin and pre-impregnated applied in the work zone. The pressurizing tooling is configured to be removably mounted on a robot and includes an articulated skeleton configured to adapt to the shape of the part around the work zone. The pressurizing tooling further includes at least one inflatable membrane which is secured to the skeleton and which is configured to apply, in an inflated state, a predetermined and uniform pressure to the work zone.

Abstract: The present disclosure provides a method for manufacturing a preform made of reinforcement fibers woven in a longitudinal direction. The preform is impregnated with resin in order to form an elongated element having a variable transverse cross-section. In one form, the method includes the step of simultaneously including a reduction (or increase) in width and an increase (or reduction) in height. The variable cross-section includes, along the length thereof, a consistent number (c) of continuous warp threads arranged in layers. The method for reducing width includes carrying out a change in weave, adding additional weft threads, and simultaneously drawing the teeth of the longitudinal beater reed closer together so as to increase the number of layers.
