Abstract
In one aspect, the disclosure relates to nanocomposite radome materials incorporating boron nitride materials in a polymer derived ceramic matrix. In another aspect, the nanocomposite radome materials have superior electrochemical performance, excellent mechanical strength and stability, corrosion resistance and transparency to electromagnetic radiation, methods of making the same, and articles and components incorporating the same. In one aspect, the nanocomposite radome materials retain functionality in the presence of significant amounts of moisture. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
Claims19
