What is disclosed is a method of preparing fiber reinforced glass composites from high modulus fibers, such as carbon fibers and silicon carbide fibers, and silazane polymers. The composites are obtained by heating a pressed and post-cured prepreg to an elevated temperature in an inert atmosphere. Prepregs containing containing silicon carbide fibers can be fired in air. Asimple, lowtemperature laminating procedure is used in the preparation of these composites in place of the standard hot pressing technique.

What is disclosed is a method of preparing fiber reinforced glass composites from high modulus fibers and resin solsoforganosilsesquioxanes, metal oxides, and metal alkoxides. The composites are obtained by firing a partially cured, pressed, and post-cured prepreg to an elevated temperature in an inert atmosphere. A simple, lowtemperature laminating procedure is used in the preparation of these composites in place of the standard hot pressing technique.

Disclosed herein are foam glasses and compositions comprising such foam glasses, which can be used, for example, in structural applications. The foam glass can have one or more properties, such as a density ranging from about 20 Ib/ft3 to about 100 Ib/ft3, a compressive strength of at least about 650 psi, and an alumina content of at least about 5% by weight, relative to the total weight of the foam glass. Also disclosed are methods for preparing foam glasses.

The invention relates to a glass ceramic armour material consisting (in % by weight in relation to oxide base) of 5-33 SiO2, 20-50 Al2O3, 5-40 MgO, 0-15 B2O3, 0.1-30 Y2O3, Ln2O3, As2O3, Nb2O3 and/or Sc2O3 and 0-10 P2O5. The inventive armour material can also be reinforced with inorganic reinforcing fibres in a quantity of 5-65 % by weight, preferably consisting of C, SiC, Si3N4, Al2O3, ZrO2 or Sialon. Said armour material is characterised in that it exhibits a high elasticity modulus and is producible from green glass without to fear a premature crystallisation.

The invention relates to friction linings for structural and functional elements used in braking systems, especially in systems for motor vehicles. Said friction linings consist of an inorganic composite material which in turn consists of a glass or glass ceramics matrix, inorganic reinforcing fibers and one or more fillers, including one or more anti-friction substances with planar hexagonal structural elements.
