A process for the production of sandwich structures made of fiber-reinforced ceramics, the base substance of the ceramic matrix consisting of a Si-organic polymer and a ceramic or metallic powder. A cross-linking of the Si-organic polymer takes place under increased pressure and at an increased temperature. After the joining of the facings and the honeycomb core, the sandwich structure is pyrolysed to form a ceramic material.

Process for producing sandwich structures from fiber-reinforced ceramics

A part or component made of a fiber re-inforced compound and having some hollow or concave portion which is not to be metallized, is provided with a wall extension adjacent the hollow or concave portion not to be metallized, which is closed and sealed off. Prior to metallizing the compound is cleaned, metal is electrolytically deposited on at least some of the outer surface parts of that compound and subsequently, the closure as well as the wall extension is removed.
