Abstract

L'invention concerne un procédé de fabrication d'une pièce tridimensionnelle pour un aéronef, ladite pièce étant d'un seul tenant et renforcée par des fibres. Selon l'invention, on produit ladite pièce par moulage de fibres de renforcement et d'une mousse (12) de polyuréthane (PUR) et/ou d'une mousse (12) de polyisocyanurate (PIR), au moins certaines desdites fibres de renforcement étant des fibres courtes intégralement positionnées dans ladite mousse (12) de polyuréthane (PUR) et/ou mousse (12) de polyisocyanurate (PIR).
