A composite material comprises a plurality of cores of material selected from the group comprising carbides, nitrides, carbonitrides, cemented carbides, cemented nitrides, cemented carbonitrides and mixtures thereof, dispersed in a matrix. The matrix comprises the components for making an ultra-hard material, such as diamond or cBN abrasive particles, and a suitable binder. The ultra- hard material is polycrystalline in nature and is typically PCD or PcBN. The cores are typically provided as individual particles or in the form of granules. The granules may be further coated with a second coating, which may be a similar material to that of the cores or of an ultra-hard material of a different grade to that of the first coating. The composite material typically takes on a honeycomb structure of a hard material and cores within the pores of the honeycomb structure bonded to the honeycomb structure. The pores of the honeycomb structure may be ordered or random. A method of producing the composite material and a method of producing a tool component incorporating such a material are also provided.

L'invention concerne un matériau composite comprenant plusieurs noyaux de matériau choisis dans le groupe des carbures, des nitrures, des carbonitrures, des carbures métalliques, des nitrures métalliques, des carbonitrures métalliques et des mélanges de ceux-ci, dispersés dans une matrice. La matrice comprend les composants permettant de produire un matériau ultra-dur, par exemple des particules abrasives de diamant ou de cBN, et un liant approprié. Le matériau ultra-dur est de type polycristallin, généralement du PCD ou du PcBN. Les noyaux sont fournis généralement en particules individuelles ou sous la forme de granules. Ces derniers peuvent en outre être enrobés d'un second revêtement, qui peut être un matériau analogue à celui des noyaux ou d'un matériau ultra-dur d'une qualité différente de celle du premier revêtement. Le matériau composite prend généralement sur une structure alvéolaire d'un matériau dur et des noyaux dans les pores de ladite structure collés à cette structure. Les pores de la structure alvéolaire peuvent être ordonnés ou aléatoires. L'invention concerne également un procédé de production du matériau composite et d'un composant d'outil incorporant un tel matériau composite.
