TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Woven TPS (WTPS) is an attractive option for thermal protection because it allows for a design to be tailored to a specific mission ? material composition can be adjusted by weaving different fiber types together and controlling their placement using computer-controlled, automated, 3D weaving technology. NASA?s HEEET program is responsible for the development of WTPS, with the objective of enabling a broad range of missions. With complex material systems such as WTPS, there exists a need for in situ Structural Health Monitoring (SHM) capability designed to diagnose and report any degradation in the capability of the structure. The primary objective of the proposed effort is to leverage MR&D?s micromechanics-based Program Suite to interpret measured temperature and strain data derived from fiber optic sensors that are structurally integrated in a 3D woven composite panel. Specifically, measured strains at the constituent level will be used to compute a local stress state in several 3D woven composite test specimens under a variety of thermal and structural loads. Measured temperature data will dictate which temperature-dependent constituent material properties to use in the micromechanics model. The proposed research offers a software solution for providing a physics based interpretation of sensor data acquired at the constituent level of a 3D woven structure and computes an effective composite level response for the purposes of evaluating structural health in near real time.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The successful completion of the Phase I program would directly benefit the Adaptable, Deployable Entry and Placement Technology (ADEPT) program as well as the HEEET Woven TPS program, both of which are currently focused on the use of 3D weaves in ablative TPS. The pairing of fiber optic sensor measurements with analytical software tools ? which can rapidly translate measured yarn-level strain and temperature changes to compute a composite level response ? allows for a robust, widely applicable, SHM tool.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There are potential applications of the SHM software tool developed under the proposed effort to be used within the Department of Defense (DoD). The use of 3D woven preforms in ballistic armor applications creates a need for real-time SHM focused on diagnosing and reporting degradation to a composite system.
