Here's the thing. This idea is in no way new. I first proposed it about a year ago. My original formula is the one we can use and make.
-Solvent
-polystyrene
-rubber cement
Let me explain. We don't need a fiber that is as strong as steel, we need one that is as strong as nylon.
The tensile strength of nylon is 45-75 Mpa. The tensile strength of polyester is 55 Mpa. The tensile strength of polyethylene is 26-37 Mpa. Steel is anywhere from 500-5000 mPa.
So for our purposes, we only need something as strong as polyethylene. PValcohol is only 15 Mpa. Styrofoam is actually 50 Mpa.
Now for the glue. Look at any sidewalk. You'll find a slight elastomeric compound that is almost impossible to get off. It's gum. The gum is actually making a molecular bond with the cement. It's the same reason it's impossible to fully remove from your hair. It bonds to specific oils. The gum base is the same stuff in rubber cement.
Now let's bring it together now. A material with the tensile strength of nylon is also very inflexible. A material that highly elastomeric and adhesive has 10 Mpa for a tensile strength. When you put them together, you have a glue that bonds makes the plastic flexible, and it bonds specifically to cement, wood, and hair without heat or a chemical reaction.
Now here is where it gets difficult. I've never tested this formula. Well, never on a large scale. It behaves like webbing in threads, but I've never tried it in full form for two reasons.
I never had a shooter.
the solvent would destroy the shooter if I had one.
But now I think I could try it. I know how to make the shooter now. The real question is how to use the shooter to make the formula work. The formula, when dried (when blended properly) should have the bare minimum properties that you need. Now, here's the deal. How do we make the solvents evaporate?
CO2
Co2 in liquid form has been known to act as a hydrocarbon solvent. That means that, if you get it in the right state, it will act like acetone. It's also a propellant. That means, all you have to do is this: use a solvent like d-limonene to dissolve the contact cement and styrofoam. Mix them well in the shooter's canister. Let the solvent evaporate and then compress the co2 in the shooter. Compress it until it becomes a liquid. Then you have silly string with 50 Mpa (maybe a little less because of the rubber) tensile strength. Then you have to force it through a spinneret.
Now let's say that you don't want to deal with that solvent nonsense. If you are willing to build a web shooter that has an inner heating source, it doesn't take a lot of heat to melt both of those things as well. If your shooter has an internal heating source, then you can release it and the CO2 will cause it to solidify once it leaves the spinneret.
Do what you want, but I'm pretty sure that the formula will work. It will be environmentally unfriendly, and it will only be so strong, but I think as the starter, it will work.
