Description
Low-density ablative materials commonly used for Thermal Protection Systems
(TPS) are composed of a porous, brous structure. Most recent studies on these ma-
terials have been dedicated to the thermal properties and thermochemical behavior. In
recent years, new studies have begun to focus on their mechanical behavior. These stud-
ies argue that in order to correctly predict failure of TPS, it is essential to model both
the thermal and mechanical response of these materials. The current research activity
proposes to use Stochastic s-RVE properties accounting for the large variabilities in these
materials. This will lead to a better understanding the eects of inhomogeneities on
the structural response of TPS at the mesoscale level by using mechanical properties at
the microscale (ber-scale) based upon synthetic representative elements derived from
micro-CT images of real materials. Upon completion, the proposed work could lead to
direct implementation in NASA production codes, and be extended to address the ef-
fects of inhomogeneity at the mesoscale on other mechanical, thermal, thermochemical,
and gas dynamical properties of TPS. This methodology could also directly lead to the
development of new TPS materials where the properties are tailored to specic material
behavior and can be used to inform additive manufacturing techniques.
