Abstract (en)

[origin: WO9406582A1] A process for producing fiber composite precision castings is disclosed. At least a preliminary pattern body, which is then used as part of a pattern or the pattern itself, is produced with fibers and with a pattern material. A ceramic mold is then formed around the pattern. The pattern material is then removed and liquid, liquid-solid or powdery metal is introduced into the mold; when powdery metal is introduced into the mold, it is at least partially liquefied. This process allows precision castings having an increased resistance to be produced with a relatively simple casting equipment.
