Abstract (en)
[origin: WO2014044963A2] The present invention relates to a method for manufacturing composite parts, and further relates to manufacturing equipment implementing such a method and to resulting composite parts. The invention is useful in the field of aircraft construction. During a first phase, the part is designed, the geometry is computed, and the fabric architecture of the fabric preform and a mandrel for forming the first state of the preform are calculated. During a second phase, the preform fabric (21) and the mandrel (20), both calculated in the first phase, are produced. During a third phase, the mandrel is wrapped with the manufactured fabric, the preform is extracted from the mandrel thereof in order to collapse (R) a portion (29b") of the preform, and finally, the preform is impregnated in order to obtain the desired composite material part.
