    摘要: A light-weight, heat distortion resistant laminate includes at least one layer of an alkali silicate resin composition derived from an alkali silicate and/or alkali silicate precursor, at least one oxoanionic compound or a reactive acidic glass; and water; and at least one reinforcing core layer comprising an inorganic high-temperature resistant composition. The laminate has a very low quench steepness index value upon rapid quenching as with ambient temperature water.

    摘要: A modified alkali silicate composition for forming an inorganic network. 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 oxoanionic compound such as phosphoric acid, water and optionally one or more multivalent cation(s) selected from Groups 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16 of the periodic table such as an alkaline earth salt, water and optional processing aids. An inorganic matrix composite can be prepared by applying a slurry of the modified aqueous alkali silicate composition to a reinforcing medium and curing the composite at a temperature from about 15° C. up to 1000° C. and a pressure of up to 20,000 psi for typical high-performance organic polymer processing (temperatures about 15° C. to about 200° C. and pressures

    摘要: Fiber-reinforced polymer composites possessing improved damping ability are provided. In one aspect, the fibers provide the composite with a relatively high dynamic modulus over a broad range of frequencies for a given temperature. In another aspect, the polymer may comprise a viscoelastic polymer possessing a relatively high loss factor for a given frequency and temperature. The polymer may be further tailored to control the center frequency at which the maximum loss factor of the polymer is achieved. The composite so formed exhibits a relatively small reduction in loss factor with significant increase in dynamic modulus over a broad range of frequencies for a given temperature. As a result, a structure damped by the composite exhibits a relatively high, constant loss factor as compared to conventional damping materials. Thus, embodiments of the disclosed composites dissipate significantly more energy during each vibration cycle than conventional damping materials.
