A method for the preparation of a composite material as well as composite material, composite material body and the connecting device

摘要

The present invention relates to a process for the preparation of a composite material or composite material body or composite body, consisting of a carbon-containing material, in particular a carbon nano material, and a metallic material, as well as a composite material, a composite material body, a composite body. In order to provide a composite material, which is as good as possible and, as far as possible, isotropic thermal conductivity properties, the method includes the steps of: producing a layer stack of two or more layers, wherein at least one of the layers in the form of a carbon-containing precursor is formed and wherein at least one layer in the form of a metal-containing matrix layer is formed; heating of the layer stack to a specific process temperature, in which the matrix layer is melted; complete infiltration of the precursor with molten matrix material; and cooling of the resulting composite material. Such a composite material can, for example, in conjunction with connecting devices are used for semiconductor devices.
