Method for producing fibrous monolith composites includes the steps of: creating first and second uniformly suspended compositions; warm pressing the compositions to create a feed rod (20); and extruding (24) the feed rod through a deposition nozzle onto a mechanically−controlled surface (26). The compositions further contain thermoplastic polymer binder and thermoplastic plasticizer.

L'invention concerne un procédé de production de composites fibreux monolithes comprenant les étapes suivantes : créer une première et seconde compositions suspendues uniformément, effectuer un pressage à chaud desdites compositions pour créer une barre d'alimentation (20) et extruder (24) ladite barre d'alimentation au moyen d'une buse de dépôt sur une surface commandée mécaniquement (26). Lesdites compositions contiennent de plus un liant polymère thermoplastique et un plastifiant thermoplastique.
