Abstract
A new material, based on a thermally-stable amorphous aluminophosphate composition (CerablakT), was investigated in Phase I, and demonstrated highly desirable dielectric properties suitable for next-generation hypersonic radomes. CerablakT is a low cost, solution derived material which has a unique glass structure that is resistant to crystallization even at elevated temperatures. Building on the Phase I results, the Phase II effort will investigate processing techniques to fabricate mechanically robust bulk materials including demonstration of subscale radome shape followed by full-scale demonstration in Phase II option. The key properties for a hypersonic missile radome material are high strength, low dielectric constant, and rain erosion resistance over a range of temperatures experienced during flight. ATFI will work closely with a DOD Prime Contractor and the Navy to demonstrate scalability and property optimization. Phase II effort will include evaluation of material architectures with the goal to meet dielectric, thermo-mechanical, and rain erosion protection property requirements. Progressive development via fabrication of small coupons to large panels to subscale development is planned with downselection to the most suitable architecture that meets Navy requirements.
