What is it about?

Ceramic Matrix Composites (CMCs) drew unprecedented attention due to their extraordinary performance under severe conditions. These exceptional properties in a single composite system open up a broad application range such as aerospace structures, propulsion parts, automotive components, optical hardware, and nuclear reactors. These CMCs are vital for re-entry and interplanetary man missions being undertaken by various space agencies like ISRO, NASA, ESA, etc.

Why is it important?

CMCs can be categorized into various types such as C/C, C/C-SiC, C/SiC, etc. The oxidation resistance of these composites in the air is vital, as far as performance re-entry conditions are considered. In this paper, the authors studied the oxidation behavior of the composites without any protective coating. The pros and cons of each composite type are discussed in detail.


This study aims at a comparative assessment of the oxidation behavior of these CMCs upto 1500°C in constant flow of air, to establish the role of SiC content in the matrix.
