ABSTRACT:
A structural panel having superior insulating properties which comprises a sheet of polyimide foam material having a metal layer on at least one surface, the metal layer being diffused into the foam structure, providing a superior metal-to-foam bond. The polyimide foam has excellent insulating and structural properties and is highly resistant to high temperatures and open flames. The metal layer adds considerable structural strength, since the diffusion of metal into the foam produces a three-dimensional metal structure rather than the usual planar surface film. The metal layer is applied to the foam sheet by chemical vapor deposition under conditions which improve the diffusion of the metal into the foam.
