Beschreibung
Zusammenfassung:	A method is described for forming composite articles comprising thermoset silicon-containing polymers, that includes (a) providing a first composition comprising a first thermoset silicon-containing polymer; (b) providing a thermoplastic composition; (c) printing a first at least partial layer of the first composition comprising the first thermoset silicon-containing polymer using an additive manufacturing device; and (d) printing an at least partial reinforcing layer comprising the thermoplastic composition using an additive manufacturing device. An apparatus for preparing a composite article comprising thermoset silicon-containing polymers that includes an additive manufacturing printer, wherein the additive manufacturing printer is capable of providing two or more layers to form a three-dimensional composite article according to a computer design model. La présente invention concerne un procédé de formation d'articles composites comprenant des polymères thermodurcissables contenant du silicium. Ledit procédé consistant : (a) à utiliser une première composition comprenant un premier polymère contenant du silicium thermodurci ; (b) à utiliser une composition thermoplastique ; (c) à imprimer une première couche au moins partielle de la première composition comprenant le premier polymère contenant du silicium thermodurci à l'aide d'un dispositif de fabrication additive ; et (d) à imprimer une couche de renforcement au moins partielle comprenant la composition thermoplastique à l'aide d'un dispositif de fabrication additive. Un appareil de préparation d'un article composite comprenant des polymères thermodurcis contenant du silicium qui comprend une imprimante de fabrication additive, l'imprimante de fabrication additive pouvant utiliser au moins deux couches pour former un article composite tridimensionnel selon un modèle de conception informatique.
