Abstract:

Ceramic structure having porosity of 10-80 is characterized by a solid ceramic matrix having therein elongated and parallel channels, the structure is made by a process that includes the steps of a arranging tows of elongated fibers parallel to each other to form a fiber preform, b contacting the fiber preform with a matrix precursor whereby the matrix precursor deposits around the fibers, c removing the fiber preform from the matrix precursor, d drying the fiber preform, e calcining the fiber preform, f hot pressing the structure containing the fugitive fibers therein, and g removing at least some of the fibers to form channels in the structure.
