Carbon-carbon vs. UP
Carbon-carbon and UP belong to fundamentally different material chemistries. Carbon-carbon is a ceramic material, while UP is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is carbon-carbon and the bottom bar is UP.
