Abstract

A laminate apparatus for engaging a fluid includes a structural medium made from plies bonded together with a resin. The structural medium defines a fluid facing surface. The laminate apparatus further includes a liner membrane bonded to the fluid facing surface of the structural medium with the resin. The liner membrane has one or more of a desired barrier characteristic and a desired chemical compatibility characteristic with respect to the fluid.

Claims

1. A method for manufacturing a laminate apparatus for engaging a fluid, the method comprising:

installing a structural medium in a structural mold, wherein the structural medium comprises resin infusible plies, the structural medium further having a first surface and a second surface opposing the first surface, wherein the second surface engages the structural mold;

extending a liner membrane about the first surface of the structural medium and sealing the liner membrane to the structural mold to form, in conjunction with the structural mold, a vacuum enclosure about the structural medium, wherein the liner membrane is the outermost layer of the vacuum enclosure;

evacuating the vacuum enclosure;

infusing the vacuum enclosure with resin;

permanently bonding the liner membrane to the first surface of the structural medium to form the laminate apparatus; and

removing the laminate apparatus from the structural mold.

2. The method of claim 1, wherein the structural medium further comprises a lip disposed between the first and second surface, the method further comprising extending the liner membrane about the first surface and the lip of the structural medium before sealing the liner membrane to the structural mold to form the vacuum enclosure.

3. The method of claim 1, wherein infusing the vacuum enclosure with resin and bonding the liner membrane to the first surface of the structural medium occur substantially concurrently.

4. The method of claim 1, wherein evacuating the vacuum enclosure precedes infusing the vacuum enclosure with resin.

5. The method of claim 1, wherein the structural medium defines an opening to the laminate apparatus, wherein the method further comprises engaging a framing structure in the opening to define an enclosed inner volume of the laminate apparatus.

6. The method of claim 5, wherein bonding the liner membrane to the first surface of the structural medium further comprises pressurizing the enclosed inner volume of the laminate apparatus.

7. The method of claim 1, wherein the structural mold comprises one or more vacuum and resin injection lines that extend through the structural mold and are open to the vacuum enclosure, wherein evacuating the vacuum enclosure and infusing the vacuum enclosure with resin comprise coupling a vacuum source and a resin injector to the one or more vacuum lines and resin injection lines, respectively.

8. The method of claim 7, wherein the liner membrane is free from the one or more vacuum and resin injection lines.

9. The method of claim 1, wherein the laminate apparatus is a cryogenic fluid containment vessel and the fluid is a cryogenic fluid.

10. The method of claim 1, wherein the structural medium further comprises reinforcing fabric plies.
