High Temperature, High Stress GPS Antenna Window

DOD / NAVY
The development of guided munitions offers interesting challenges in system, component, and materials design. Indeed, system requirements drive component requirements which, in turn, drive material requirements. A prime example of this linkage may be seen in the component of focus for this proposed effort; a GPS antenna. The primary functionality of these components, EM transparency for tracking and guidance communications, is coupled with severe environmental and thermo-structural loading conditions. As a result, holistic material design is seen as an absolute necessity. In brief, this program proposes to advance antenna window materials technology for applicability to a new class of rapid launch munitions. The Phase I program will investigate the viability of select fibrous ceramic composites in meeting the defined requirements. To mitigate risk, an established antenna window material system is proposed as a baseline. Material property and performance enhancement schemes focus on fiber architecture, matrix composition, and densification approach. The material systems will utilize a tailored three-directional fiber architecture to help meet directional property requirements. The candidate material systems will be manufactured in plate form, with a thickness representative of the antenna window, and test samples extracted. Testing will include mechanical, thermal, and dielectric property evaluation, and inertial load performance.
