  • Composites for protecting signal transmitters/receivers
    Patent number: 10662304
    Abstract: 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.
    Type: Grant

  • Cyanate resin blends and radomes including them
    Patent number: 10329383
    Abstract: 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° C. and a moisture absorption of less than 1.5%. Radomes using the resin are also described.
