Abstract

La présente invention concerne un procédé et un moule de formage (10) de matériau composite comprenant une empreinte positive (12) et une empreinte négative (14) adaptées à être entraînées l’une vers l’autre tandis qu’une plaque d’un matériau composite thermoplastique ramollie (46) est engagée entre lesdites empreintes pour pouvoir presser ladite plaque de manière à former une pièce en creux (58) présentant un fond (60) et un bord (61). Ladite empreinte négative (14) comprend une partie centrale négative (22) et une partie périphérique négative (24) mobile en translation par rapport à ladite partie centrale négative (22). Et ladite partie centrale négative (22) et ladite partie périphérique négative (24) sont adaptées à être entraînées successivement en translation de manière à presser ladite plaque (46) pour former ledit fond (60), tandis que ladite partie périphérique négative (24) vient former ledit bord (61) après que ledit fond (60) a été pressé. Figure à publier avec l’abrégé : Fig. 1The present invention relates to a method and a mold (10) for forming a composite material comprising a positive cavity (12) and a negative cavity (14) adapted to be driven towards each other while a plate of a softened thermoplastic composite material (46) is engaged between said cavities in order to be able to press said plate so as to form a recessed part (58) having a bottom (60) and an edge (61). Said negative imprint (14) comprises a negative central part (22) and a negative peripheral part (24) movable in translation with respect to said negative central part (22). And said negative central part (22) and said negative peripheral part (24) are adapted to be driven successively in translation so as to press said plate (46) to form said bottom (60), while said negative peripheral part (24) comes to form said edge (61) after said bottom (60) has been pressed. Figure to be published with abstract: Fig. 1
