Carbon-carbon vs. CA
Carbon-carbon and CA belong to fundamentally different material chemistries. Carbon-carbon is a ceramic material, while CA is polymeric. 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 carbon-carbon and the bottom bar is CA.
