Tooling apparatus for forming a composite charge into a contoured composite blade stringer includes an elongate punch and an elongate die flexible along their lengths. The charge is press formed by using the punch to drive the charge into the die. The punch and the die are mounted between a pair of flexible plates. A press coupled with the plates contours the charge by bending the plates into a desired contour.

    Un appareil doutillage pour la mise en forme dune charge composite en un longeron composite profilé comprend un poinçon allongé et une matrice de forme allongée flexibles le long de leur longueur. La charge est formée par pressage en utilisant le poinçon pour enfoncer la charge dans la matrice. Le poinçon et la matrice sont montés entre une paire de plaques souples. Une presse couplée aux plaques entoure la charge en pliant les plaques au contour désiré.
