Summary

Published chemical vapor infiltration (CVI) methods for the rapid densification of functional, high-temperature, fiber-matrix composites, such as C-C and SiC-SiC, are reviewed. In particular, three thermal-gradient CVI methods - (1) inductively-heated flowing-gas isobaric, (2) liquid-immersion inductively-heated isobaric and (3) radiantly-heated forced-flow - are contrasted to the conventional but slower isothermal, isobaric CVI. All approaches are summarized in a comparative table.
