The invention relates to a method for producing a composite body and to a composite body produced using the method, wherein the composite body () is formed as a pressure pipe or as a pressure container, wherein the composite body is composed of a main body () that is made of steel and of a coat () that is made of a fiber composite (), said coat enclosing the outside of the main body at least in some sections, wherein, for forming the fiber composite, a fibrous material is wound around the main body, wherein the fibrous material is impregnated with a resin before or after winding, wherein the wound and impregnated fibrous material is heated in order to form the fiber composite, wherein the method is carried out in situ on a built-in pressure pipe or pressure container, wherein the wound and impregnated fibrous material is heated to up to 700&#xb0; C.

Method for producing a composite body

A method for the production of a ceramic substrate for a semiconductor component, includes the steps of producing paper containing at least cellulose fibers, as well as a filler to be carbonized and/or SiC, pyrolizing the produced paper, and siliconizing the pyrolyzed paper.

Method for the production of a ceramic substrate, and a ceramic substrate

A support for structural components that are subjected to a thermal treatment process. The support includes a frame having limbs and extending therefrom a grid of intersecting strands. In order to prevent the support from warping even when subjected to strong thermal loads or variations in temperature, the frame is produced from a temperature-resistant material and the strands are produced from carbon fibers or ceramic fibers that form the grid, extending from the limbs of the frame.

Support for structural components and method for producing the same

A method for the production of a carbon or a ceramic component based on carbon, using a cellulose-containing semi-finished molded piece which is pyrolyzed. According to the invention, homogeneous large-size ceramic components may be produced, whereby a cellulose-containing, semi-finished molded piece containing fibers, chips or strands of homogeneous density distribution and homogeneous structure is used as semi-finished molded piece and is pyrolyzed in non-oxidizing gas atmospheres.

The invention involves a rotary anode of an x-ray tube with a cooling element of carbon fiber material constructed so as to be rotationally symmetrical around a coaxial rotation axis. In order to achieve a high heat conducting capability, it is recommended that the base of the cooling element () be a preform constructed according to the tailored fiber placement process (TFP), that the cooling element have a hollow cylinder and a one-piece construction, that the carbon fibers () run parallel along its entire length or basically parallel to the axis () and have a heat conductivity &#x3bb; with &#x3bb;&#x3e;/=250 W/m&#xd7;K, and that the carbon fibers be connected across a matrix containing carbon whose graphite crystallites are aligned along the carbon fibers.

Rotary anode as well as a method for producing a cooling element of a rotary anode

A composite ceramic body includes a fiber-reinforced core region containing carbon, and a surface region containing SiC. In order to produce a composite ceramic body having good long-term behavior, the proportion of SiC contained in the body varies continuously, or essentially continuously, from inside the core region towards the surface region.
