This is just an example of a bungee cord extruding apparatus. It says that the average width of the the bungee cord can be anywhere from the thickness of a pencil, or the thickness of three pencils. That's about what peter's webbing was. The difference is that bungee cords don't contain the reinforcement because they want so much stretch. Since we don't need as much, this will work great for us. does that look familar to the examples up there? One final problem that I won't be able to solve quite yet is how to mix the ingredients in a way that they are evenly distributed. I believe that to do this, you must mix them all in powdered form, heat it so the rubber will bond to everything, let it solidify, and then add the solvent. In the case of plastic steel, and the artificial webbing using polyurethane, they mixed materials by solvent control. That might be something to look into. http://www.sciencecodex.com/u_m_research_new_plastic_is_strong_as_steel_transparent http://www.sciencedaily.com/releases/2007/01/070119115103.htm Anyway, now that I've gotten all of the basic research that you guys need in there, I open this forum to you.
