TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Heat shield technology is a critical component for both re-entry and
hypersonic vehicles. The traditional manufacturing approach for
designing heat shields consists of joining TPS tiles together with an
adhesive that fills any gaps between them. This approach has significant
challenges, including the reduction in thermal-mechanical performance as
compared to that of acreage woven material. Nhung's Notions proposes to
address this problem by modifying existing equipment to mechanically
join these materials prior to infusion. In Phase I, we will determine
the material and pattern parameters required to use with equipment to
prepare the joins while minimizing damage to the pristine woven material
while maintaining consistent thickness between pre- and post- joined
material keeping pattern consistency throughout the process.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The completion of the project will result in a method for joining and
repairing mid-to-high density ablative TPS materials of at least 1"
thickness. This project will provide new ways of adequately designing
large and/or complex shapes for heat shields to protect the spacecraft,
enabling operation under harsher conditions with a reduction in both
weight and cost.
The next generation of crew reentry vehicles being designed by NASA will
require more advanced Thermal Protection System (TPS) designs than the
conservative approaches currently used. While new TPS materials are
under development, a key difficulty is the ability to create the joining
seam TPS material which is not reduce the thermal-mechanical performance
compared TPS woven material. This project helps address that difficulty.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
As our society becomes more dependent upon satellites for worldwide
communications, weather prediction, global positioning, and countless
other applications, the need to be able to add, service, replace, and
remove satellites grows, and with it the need for more efficient
commercial re-entry vehicles capable of performing these tasks. This
project helps enable these vehicles as well as the more exotic
exploration vehicles.
