  • Process for producing sandwich structures from fiber-reinforced ceramics
    Patent number: 5632834
    Abstract: 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.
