Abstract
Fiber-reinforced ceramic honeycomb is prepared by impregnating a high-temperature fiber, notably fibers of ceramic materials such as silicates, aluminosilicates, aluminates and silicon carbides, with a liquid solution or suspension of a ceramic precursor material, followed by forming the impreganted fiber into corrugated strips, assembling the strips into the honeycomb structure, then heating the strips to form the ceramic. Multiple impregnations with intervening heating are useful in controlling the density and quality of the product.
