<p>A modified alkali silicate composition for forming an inorganic network matrix. The modified alkali silicate matrix is made by reacting an alkali silicate (or its precursors such as an alkali hydroxide, a SiO2 source and water), an acidic inorganic composition, such as a reactive acidic glass, water and optional fillers, additives and processing aids. An inorganic matr ix composite can be prepared by applying a slurry of the modified aqueous alkal i silicate composition to a reinforcing medium and applying the temperature an d pressure necessary to consolidate the desired form. The composite can be shaped by compression molding as well as other known fabrication methods. A notable aspect of the invention is that, although composite and neat resin components prepared from the invention can exhibit excellent dimensional stability to 1000~C and higher, they can be prepared at the lower temperatur es and pressures typical to organic polymer processing.</p> |
