  • Process for making a low density foam filled reticulated absorber by means of vacuum
    Patent number: 6231794
    Abstract: A method for making an improved absorber entails the loading of reticulated foam loaded with radar absorbing material and the forming and curing of the loaded foam in a mold on which vacuum is impressed prior to curing of the foam so that the foam expands and thereby experiences a substantial reduction in density of the resulting absorber structure.

  • Normal incidence multi-layer elastomeric radar absorber
    Patent number: 6224982
    Abstract: A method for making an improved radar absorbing structure which includes forming a stack of layers of elastomeric sheet material, at least one of which supports conductive material, with a layer of dielectric material, shaping the stack, and curing the shaped stack. The stack of layers has a thickness of no more than 0.1″, and may be wrapped about a mandrel or fitted to another forming body to impart a final, complex, shape to the stack, and then cured.
