ABSTRACT:
An improved method for the fabrication of lightweight ceramic matrix composite panels, utilizing pressure forming with floating tooling to shape integral stiffeners such as raised integral surface channels on panel surfaces. The consolidation of green composite material against refractory floating tools by hot hydrostatic or isostatic (gas) pressing, followed by removal of the tooling, yields a strong, rigid, yet lightweight ceramic structure.
