Abstract
An intermediate member is formed as a semifinished product and includes at least two films or sheets of carbon containing material. Both sheets, such as prepegs, are initially in a still deformable state. One film or sheet is plane, the other is profiled and then the two are bonded to each other, brought into the desired final form and cured. The final form is then heated while air is excluded for coking the carbon so that only a carbon skeleton remains. Such skeleton may be further reinforced by again impregnating the skeleton with a carbon containing resin and again coking. The carbonized or coked final form is enriched by metallic silicon, whereby the silicon precipitates by decomposition. Simultaneously with the enriching step or thereafter the final form is heat treated again to cause the formation of silicon carbide by the reaction C+SI.fwdarw.SiC.
