CA vs. Carbon-carbon
CA and carbon-carbon belong to fundamentally different material chemistries. CA is a polymeric material, while carbon-carbon is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (27, in this case) are not shown.
For each property being compared, the top bar is CA and the bottom bar is carbon-carbon.
