  I have the above properties of a brake pad material which are not inbuilt in the engineering data sources. How do i get results of fatigue when the material isn't already in ANSYS workbench given that i don't have the S_N curves of the material?.

  You can perform your own lab experiments to collect data to construct SN curves or you can find data in the literature.

  unfortunately i haven't been able to come across brake pad materials with those details, would you be kind as to share some if you know any?

  I have no data on brake pad materials but I have collected my own SN data in lab tests for other materials.
