Assembly and mounting of a reflective film on a composite structure
View Patent ↗A method of metallizing a surface of a structure, and in some embodiments a mirror produced by such method, by the steps of providing a composite support structure; providing a release liner including a metallic layer having a thickness between 1 and 5 microns on a surface thereof; situating the release liner against the surface of the composite support structure so that the metallic layer of the release liner is placed in direct, physical contact with the surface of the support structure; and removing the release liner so that the metallic layer remains attached to the surface of the support structure.
1. A method of metallizing the surface of a structure to form a mirror for use on a space vehicle, the method comprising:
providing a composite support structure having a surface, wherein the composite support structure comprises a fiber selected from the group of consisting of: carbon fiber, glass fiber, polyamide fiber, stainless steel fiber, copper fiber, boron fiber, and amorphous metal fiber;
providing a release liner comprising a polymer sheet and a metallic layer having a thickness between 1 and 5 microns on a surface of the polymer sheet;
situating the release liner against the surface of the composite support structure so that the metallic layer is in direct, physical contact with the surface of the composite support structure; and
removing the polymer sheet so that the metallic layer remains as a reflective metal film attached to the surface of the composite support structure.
2. A method as defined in claim 1 , wherein the difference in tensile strength between the composite support structure and the release liner is sufficiently great that allows the release liner to be peeled from the metallic layer which remains attached to the support structure.
3. A method as defined in claim 1 , wherein the composite support structure is composed of a carbon fiber composite material having a thickness of between 1 and 20 mil.
4. A method as defined in claim 1 , wherein the release liner is composed of a poly (4, 4′-oxydiphenylene-pyromellitimide) material.
5. A method as defined in claim 1 , wherein the metallic layer comprises aluminum.
6. A method as defined in claim 1 , wherein the metallic layer has a uniform thickness and covers the entire exterior surface of the composite support structure.
7. A method as defined in claim 1 , wherein the composite support structure with the metallic layer forms a mirror adapted for implementation on a space vehicle.
8. A method as defined in claim 1 , wherein the removing step is performed manually.
9. A method as defined in claim 1 , wherein the composite support structure includes a non-uniform exterior surface with certain regions being concave and other regions being convex.
10. A method as defined in claim 1 , wherein the release liner has a thickness of between 25 and 100 microns, or between 1 mil (25.4 μm) and 4 mil (101.6 μm).
11. A method as defined in claim 8 , wherein the mirror is parabolic in shape.
12. A method as defined in claim 1 , wherein the composite support structure includes a plurality of layers with each layer between 0.001 and 0.20 inches in thickness.
