Hello! I'm kinda all over the place project wise (apologies Paul), but one of the things I am working on right now is a Phase 1 STTR grant from NASA for a new solar sail material.
As part of that, I'm trying to figure out the barriers to implementing a new solar sail design called a "space tow". It's composed of a bunch of little solar sails all strung together like sled dogs to pull on something. As part of that, I am trying to see whether it's possible to form corrugations in a thin plastic sheet (1-5 microns thick) so that it has some rigidity and won't need reinforcement to stay planar. As part of that, I would like to try vacuum forming one of the sheets and see if that can produce the desired change in shape. ... as part of that, I need to find, make or buy a vacuum forming machine and give it a go. TL;DR: Does anyone know where I could find a vacuum forming machine that I could use or about their experience homebrewing one? Thanks, Charlie
