Fabrication assembly and methods for fabricating composite mirror objects
A fabrication assembly comprises an apparatus that receives a composite substrate and a glass substrate having a surface with a release coating layer. A resin layer is deposited between the composite and glass substrates such that a first portion of the resin layer is positioned adjacent to a surface of the composite substrate and a second portion of the resin layer is positioned adjacent to the surface with the release coating layer to prevent aperture(s) from forming. A curing of the resin layer is conducted using electromagnetic radiation. A post-processing chamber receives the resin layer positioned between the composite substrate and the glass substrate and conducts another curing of the resin layer. The resin layer and the composite substrate are released from the glass substrate. Another deposition apparatus receives the resin layer and the composite substrate. A metallic coating is deposited to form a composite mirror object.
