Carbon-carbon vs. PPS
Carbon-carbon and PPS belong to fundamentally different material chemistries. Carbon-carbon is a ceramic material, while PPS is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 7 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is carbon-carbon and the bottom bar is PPS.
