| 摘要 |
The invention relates to polymer ceramic composite materials with a virtually zero shrinkage compared to the original model after concluding partial pyrolysis and with a comparable thermal expansion behavior (preferably in an application range of 400° C. or less) to metal construction materials, in particular gray cast iron or steel, which are obtainable by methods described below; corresponding composite constructions and molded parts; and methods for producing and using these materials, composite constructions and molded parts. The polymer ceramic composite materials can for instance be used instead of or in contact with steel or gray cast iron temperature-proof molded parts, predominantly in mechanical engineering, without postmachining after the creative forming.
