A method for producing a composite part. The method comprises compacting a powder composition comprising a lubricant into a compacted body; heating the compacted body to a temperature above the vaporisation temperature of the lubricant such that the lubricant is substantially removed from the compacted body; subjecting the obtained heat treated compacted body to a liquid polymer composite comprising nanometer-sized and/or micrometer-sized reinforcement structures; and solidifying the heat treated compacted body comprising liquid polymer composite by drying and/or by at least one curing treatment.
L'invention concerne un procédé pour produire une pièce composite. Le procédé comporte les étapes consistant à : compacter une composition de poudre comprenant un lubrifiant en un corps compacté; chauffer le corps compacté à une température supérieure à la température de vaporisation du lubrifiant, de telle sorte que le lubrifiant est sensiblement éliminé du corps compacté; mettre en contact le corps compacté ainsi obtenu avec un composite polymère liquide comprenant des structures de renforcement d'une dimension de l'ordre du nanomètre et/ou du micromètre; et solidifier le corps compacté incluant le composite polymère liquide par séchage et/ou par un ou plusieurs traitements de durcissement.
