Carbon-carbon vs. Graphite

Both carbon-carbon and graphite are non-oxide engineering ceramics. There are 13 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is carbon-carbon and the bottom bar is graphite.
