Ceramic Radome Material

The flexural strength dielectric constant and loss tangent values of various ceramic materials used in the development of radomes are important in the selection of radome materials.

Ceramic radome material. Ceramic materials show variational properties with sintering time temperature and other additives. Ceramic material is the preferred material for missile radome because of its excellent mechanical thermal and electrical properties. Corningwaretm is an example of a monolithic material similar to that used for ceramic nose radomes being a single layer inherently limits the bandwidth of the radome due to the physics of rf energy propagation. Polyurethanes are especially useful in aerospace applications where functional lightweight materials are imperative.

The glass ceramic material produced by corning since the 1950s is opaque gray in color and has high strength high elastic modulus and uniform dielectric properties. The missile radome is located at the front end of the missile. Easily optimized material allows for high performance with low dielectric interference. That is made from a single layer of material.

Corning produces a proprietary material corning pyroceram for use in missile radomes. This effort will leverage nanosonics rapidly evolving polymer derived ceramic hybridsil nanotechnology which has demonstrated thermo. Different nose cone shapes of missile radomes are also important. In all radome applications polyurethane foams offer an effective solution for cost effective materials that are both versatile and robust.

Ceramic radomes flying today are monolithic.
