Abstract: A hollow-cylindrical heat shield includes at least one graphite foil and at least one fiber structure, preferably a wound fiber structure, disposed on the outer side of the at least one graphite foil. The (wound) fiber structure has a degree of coverage of less than 100%. A high-temperature furnace or gas converter having a heat shield is also provided.

Abstract: A component made of a fiber composite material contains at least three wound layers made of a fiber material that are arranged one over the other. Each of the wound layers contains one or more windings. For each wound layer containing more than one winding, all windings of the wound layer have the same winding angle and are separated from each other in some sections, whereby intermediate spaces are formed between the windings. All windings of at least two of the wound layers have the same first winding angle. All of the windings of one wound layer, which is arranged between the two wound layers having the windings with a same first winding angle, have a second winding angle. The magnitudes of the first and second winding angles differ, and the windings having the second winding angle intersect with the windings having the first winding angle.

Abstract: A ceramic component is formed of at least one stack of two or more layers of one-directional non-woven carbon fiber fabrics embedded in a ceramic matrix containing silicon carbide and elemental silicon. All adjacent layers within the at least one stack directly adjoin each other. The at least one stack has a minimum thickness of 1.5 mm perpendicularly to the plane of the layers. The ceramic matrix permeates substantially the entire component.

Abstract: A layered composite material component has two or more layers of graphite foil. The layers of graphite foil are connected together by way of at least one connecting pin that engages in both layers in a form-fitting manner.

Abstract: A composite contains a binder, at least one layer of a soft carbon fiber felt, and at least one layer of a hard carbon fiber felt. The at least one layer of soft carbon fiber felt is joined via the binder to the at least one layer of hard carbon fiber felt.

Abstract: A tubular composite member with two ends for connecting ceramic components made of a composite of an inorganic matrix reinforced with inorganic fibers is formed with an at least partially threaded internal surface and an external surface. A ceramic member has at least one surface formed with one or more annular grooves with an inner shell surface, an outer shell surface, and a root. The inner shell surface is at least partially threaded. A resulting ceramic member assembly includes at least two ceramic members connected by at least one tubular composite member. The ends of the tubular composite member are screwed into the corresponding annular groove of two adjacent ceramic members. The such fastened/joined ceramic members can be operated at high temperatures especially under thermal cycling and/or thermal shock conditions as well as dynamic mechanical load in different directions. Methods to manufacture tubular composite members according to this invention are described.

Abstract: High-temperature-resistant composites are formed of at least two layers of high-temperature-resistant carbon-based materials or graphite-based materials. The layers are joined to one another by a carbonized binder which contains planar anisotropic graphite particles. The planar anistropic graphite particles have a high anisotropy in respect of their crystal structure and their thermal conductivity are added to the carbonizable binder.
