Embodiments of the present disclosure are directed to a composition and composite for protecting a transmission/reception device. The composite can include a reinforcing material and a cured epoxy composition impregnating the reinforcing material. The cured epoxy composition can contain reaction constituents including less than 50% stoichiometric amount of an anhydride curing agent to an epoxy resin. The composite can exhibit synergistic improvements in mechanical strength, weatherability, and signal transmission properties.

Composites for protecting signal transmitters/receivers

Certain embodiments are directed to cyanate resin blends comprising, for example, a mixture of a cyanate monomer and a cyanate oligomer. The resin blends are effective to provide a dielectric constant of less than 2.7, a glass transition temperature of at least 150&#xb0; C. and a moisture absorption of less than 1.5%. Radomes using the resin are also described.
