Radomes are constructed with glass, Kevlar, and quartz in thin skin formats as well as sandwich formats using various core material along with the skin. Core materials consist of foam or honeycomb depending on the application. Foam core materials include PMI and PU. Honeycomb core material includes glass, Kevlar, quarts, nomex, spectra etc. Various matrix of epoxy, cyanate ester, and bismaleimide are used.

“Greater strength and low weight is achieved through the use of honeycomb,” says Louis George.

The material selection criteria for composite radomes must include a minimal RF loss factor against maximum structural stability.
