A composite material containing carbon and a plastic includes: a) provision of a pulverulent composition with one or more components of amorphous carbon, graphite and mixed forms thereof, b) provision of a liquid binder, c) planar deposition of a layer consisting of the material provided in step a) and local deposition of droplets of material provided in step b) onto this layer and any number of repetitions of step c), the local deposition of the droplets in the successive repetitions of this step being adapted according to the desired shape of the component to be produced, d) at least partial curing or drying of the binder to obtain a green body that has the desired shape of the component, e) impregnation of the green body with a liquid synthetic resin and f) curing of the synthetic resin to produce a synthetic resin matrix.

A mixture for heat storage devices has a phase change material and particulate expanded graphite. The material mixtures are produced by mixing phase change material and expanded graphite as powders or in molten form, and shaping the mixtures into shaped bodies.

A latent heat storage material is in the form of a composite material formed of a phase-change material to store latent heat and graphite flakes incorporated therein to improve thermal conductivity. The graphite flakes are distinguished by a high aspect ratio and a high anisotropy of thermal conductivity. The volume content of graphite flakes in the latent heat storage material is between 10 and 40%. The composite material can be obtained by mixing the components or infiltrating a bed containing graphite flakes with a liquid phase-change material. The graphite flakes are preferably aligned during mixing with the phase-change material by shaking or tamping, etc., so that the thermal conductivity in the direction that is advantageous for the individual application is maximized. A latent heat storage unit containing the material and processes for producing the material and the unit and processes for using the material, are also provided.

A flat gasket for flange connections has a leakage rate below the limit value of 1*10kPa*1/(s*m). The gasket assembly has a thick, areal, pressure-resistant core formed from at least one layer of graphite foil with a base weight of at most 1500 g/m, or a multilayer sandwich of such graphite foils and metal interlayers. The core is embedded between two metal foils, and the surfaces that are remote from the core are covered by covering layers of graphite foil with a base weight of at most 350 g/m. A ratio of the base weight of the graphite foil of the covering layers to the base weight of the graphite foil of the core lies between 1:3 and 1:7.
