Research Institution
In this Phase I SBIR project, a low-cost oxide-oxide interface coating-free ceramic matrix composite (CMC) will be developed for radomes for next-generation high speed missiles. The innovative and key component of the CMC is a newly patented matrixmaterial (CerablakT) based on aluminum phosphate compositions. The key properties of CerablakT relevant to radome applications is its low dielectric constant (range from 2.98-4 @ 4-13 GHz) and high temperature stability. Cerablak is derived from alow-cost and clear precursor solution with a low viscosity and high yield which is highly beneficial for efficiently fabricating matrices for CMCs. Excellent have been demonstrated for CerablakT matrix CMCs with Nextel 610 and 720 reinforcements. Theseproperties include high composite strength, excellent compatibility with fillers and fibers, and high matrix density. In Phase I, CMC specimens will be fabricated using Cerablak matrices Nextel 720 fabric. Property evaluation will include dielectricconstant of composite systems, RT tensile strength, and matrix density. Based on the results, a suitable CMC system will be selected for Phase II effort. In Phase II, ATFI will work with the Navy and prime contractors of radome systems to integrate theCMC technology. Radome materials with improved properties will aid in the development of next-generation high speed missiles. CMCs have applications as structural materials in high temperature corrosive environments. Low dielectric constant materialshave many applications in electronics.
