The conformal ablative is developed based on phenolic impregnated carbon ablator, which is focused
on thermal protection materials for future mars entry, descent and landing systems. A brief historical retrospect on the
development and application of phenolic impregnated carbon ablator are carried out. The application required for con-
formal ablative is introduced. The definition, manufacturing procedure and correlative aeroheating tests for conformal
ablative are introduced in details.
