ABSTRACT:
The invention relates to a method for producing a composite from inorganic substances and binders on the basis of silane. The inventive method is characterized by the use of one or more silicon compounds of the general formula (1) as the binder, wherein R represents groups that are the same or different and that cannot be hydrolytically cleaved, and wherein X represents one or more hydroxyl groups or one or more hydrolytically cleavable groups that are the same or different, and n is a number between 0 and 3, preferably between 1 and 2. Said silicon compounds have been previously condensed with understoichiometric amounts of water per mole silicon compound in the presence of alkaline or acidic catalysts. The inorganic substances used are bundles or strands of glass and/or mineral fibers onto which the precondensed silicon compounds have been sprayed in amounts of from 1 to 20% by weight, preferably together with overstoichiometric amounts of water. The strands or bundles so treated are then brought into their final shape and are deformed or compressed to give shaped bodies.
