Beschreibung
Zusammenfassung:	A composite article can comprise a composite body including an organic polymer and ceramic particles comprising hexagonal boron nitride (hBN) particles distributed throughout the organic polymer, wherein an amount of the hBN particles ranges from 40 vol% to 90 vol% based on a total volume of the body; and the body comprises an in plane thermal conductivity of at least 15 W/mK. The hBN particles within the composite body can have a March-Dollase Orientation parameter η of at least 50%. Un article composite peut comprendre un corps composite comprenant un polymère organique et des particules de céramique comprenant des particules de nitrure de bore hexagonal (hBN) distribuées dans le polymère organique, une quantité des particules de hBN étant comprise entre 40 % en volume et 90 % en volume sur la base d'un volume total du corps; et le corps comprend une conductivité thermique dans le plan d'au moins 15 W/mK. Les particules de hBN à l'intérieur du corps composite peuvent avoir un paramètre d'orientation de March-Dollase η d'au moins 50 %.
