Kevlar also has has good damage tolerance. Carbon is very good in tension and compression has great stiffness. Kevlar-Carbon can be interwoven to provide a material that has a better overall set of properties for whitewater boats than either Kevlar or Carbon alone. Relatively strong in tension and compression, high stiffness, and a relatively high damage tolerance. Kevlar also has has good damage tolerance.
