Abstract: A thrust reverser cascade for an aircraft nacelle includes a plurality of blades having a first and a second surface, the blades being connected to members connected to attachment flanges for attaching the thrust reverser cascade to the nacelle. At least one of the surfaces of the blades is covered with at least one layer of fibers, each layer including a plurality of fiber pieces which are pre-impregnated with resin. The fiber pieces are superimposed on one another, positioned parallel to the aerodynamic surface of the blade and oriented in different directions.

Abstract: A method for producing by pultrusion a hollow main body of a rotary movement transmission shaft made of a composite material, the method including: impregnating a reinforcement; arranging a reinforcing fabric around a pultrusion chuck to wrap the pultrusion chuck, the fabric including circumferential fibers arranged in planes orthogonal to a longitudinal axis of the chuck; and then depositing the impregnated reinforcement around the reinforcing fabric.
