Abstract: A latent heat storage material is formed of at least two plies of a compressible graphitic material in which graphite wafers are arranged substantially in layer planes lying one on the other and which is infiltrated with at least one phase change material. The surface of each ply is provided with a structuring reaching the outsides of the graphite material bundle. The evacuation and infiltration travel lengths in the layer planes, due to the structuring, amounts to a maximum of 200 mm.

Abstract: A sealing material is formed as a planar laminate compound made of at least two layers of a graphite film with a maximum density of 1.6 g/cm3 alternating with at least one metal inlay. The metal inlay has a three-dimensional structure and has open depressions on one side which are covered by graphite overlays with a thickness in the range of up to a maximum of 5.0 mm. The depressions are enclosed by elevations intersecting in straight lines, and the ridge lines on both main sides lie approximately on defined planes a, b. Alternatively, the metal inlay has a hole structure both sides of which are covered by graphite overlays with a thickness in the range of up to a maximum of 5.0 mm. The holes are enclosed by webs and on both main sides lie approximately on the planes a, b. The hole area forms 40% to 90% of the total surface area of the metallic inlay.

Abstract: A flat gasket for flange connections has a leakage rate below the limit value of 1*10?5 kPa*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/m2, 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/m2. 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.
