Abstract:
1. A high-temperature heat-resistant composite material prepared by a method comprising: (a) combining a mixture of submicron alumina powder and submicron silica powder, wherein the ratio of alumina to silica is from about 4:1 to about 5:1, submicron Group II metal oxide powder, and a Group I metal silicate solution to form a slurry, wherein the weight of the Group II metal oxide powder is an amount corresponding to about 5% to about 10% of the weight of the silicate solution: (b) contacting reinforcing high-temperature resistant fibers with the slurry of step (a) to form a composite precursor composition; and (c) curing the composition of step (b) at a temperature sufficient to produce said high-temperature heat-resistant composite material capable of resisting temperatures up to about 1400° C.
