Methods for producing a flexible, fibrous ablator thermal protection material, for use in association with a space vehicle that passes through an atmosphere in which severe heating is experienced. A phenolic resin and/or a silicone resin can be used. The elastic modulus of the resulting material is low, in a preferred range of about 200-5000 kPa, and can be controlled by choice of a curing temperature and/or a time interval length for curing.
