Abstract

La présente invention concerne un procédé de fabrication d’une pièce moulée (PM) comprenant : - une fourniture (S1) dans une trémie de premiers broyats (BR1) d’éléments en matériau composite thermodurcissable et de deuxièmes broyats (BR2) d’éléments en fibre de remplissage ; - un malaxage (S2) dans un malaxeur desdits premiers (BR1) et deuxièmes (BR2) broyats pour obtenir un mélange (MIX1) ; - un ajout (S3) dans le malaxeur d’un liant (LI1, LI2) pour obtenir un mélange visqueux (MIX2) ; et - un moulage (S5) de ladite pièce moulée (PM) en introduisant ledit mélange visqueux (MIX2) dans un moule.The present invention relates to a method of manufacturing a molded part (PM) comprising: - a supply (S1) in a hopper of first shreds (BR1) of elements made of thermosetting composite material and second shreds (BR2) of elements fiber filling; - mixing (S2) in a mixer of said first (BR1) and second (BR2) ground materials to obtain a mixture (MIX1); - an addition (S3) of a binder (LI1, LI2) to the mixer to obtain a viscous mixture (MIX2); and - molding (S5) of said molded part (PM) by introducing said viscous mixture (MIX2) into a mold.
