An aircraft wing slat (20) is formed from composite materials using lay-up and vacuum bagging techniques. The slat lay-up comprises a central honeycomb core (26) sandwiched between upper,(22) and lower (24) composite skins, a pre-cured (28) spar and pre-cured stiff eners (30). After the lay-up is cured and removed from a lay-up mold, leading edge strengthening ribs (32) and a preformed composite nose skin (40) are installed to complete the slat.

L'invention concerne un bec de bord d'attaque d'avion formé à partir de matériaux composites utilisant des techniques d'empilage et de collage à la poche sous vide. L'empilage de bec de bord d'attaque comprend un noyau central en nid d'abeilles pris en sandwich entre des peaux composites supérieure et inférieure, un longeron précuit et des raidisseurs précuits. Après que l'empilage ait été cuit et retiré d'un moule d'empilage, des nervures de renforcement de bord d'attaque et une enveloppe de nez composite préformée sont installées pour achever le bec de bord d'attaque.
