摘要：A radome structure has an outer first layer of a fiber-reinforced compositematerial of quartz fibers in a noncrystalline cured oligomeric cyanate ester pre-polymer.A second layer of a syntactic foam underlies and is bonded to the first layer. A third layerof the same fiber-reinforced composite material (although possibly of differentthickness) underlies and is bonded to the second layer. A fourth layer of the syntacticfoam underlies and is bonded to the third layer. A fifth layer of the same fiber-reinforcedcomposite material (preferably of the same thickness as the first layer) underlies and isbonded to the fourth layer. The structure is formed by layup of the first layer inside afemale mold, and successively shaping the remaining layers and tacking them to eachpreceding layer. The shell produced in this manner can be joined to conforming shells.
