Abstract
The invention relates to a process for the manufacture of a solder joint between a part consisting of pyrolytic graphite and a metal part. According to the invention, the parts are not soldered directly to each other, but by way of an intermediate piece consisting of graphite reinforced with carbon fiber. In the process, pyrolytic graphite and carbon-fiber reinforced graphite are positioned in relation to each other in such a way that the stratification of pyrolytic graphite runs approximately parallel to the place of primary orientation of carbon fibers within the carbon-fiber reinforced graphite.
