Yes, I can! There are equally as many variants of glas and aluminum, yet the underlying chemistry is always the same. I dare you to permanently bend a glass pane at normal temperatures without breaking it. Also find me a translucent radio-transparent aluminum alloy. You have thousands of varieties to choose from.
Ask your mother for some kitchen foil to test your theory that thickness and frangibility of a material have nothing to do with each other. The Pentagon will make you a billionaire, if you build them indestructible tinfoil tanks.
You made the comment that plastic has to be made ‘thick’ in order for it to be durable and that is false. I’ve been designing with plastics and metals for nearly 20 years and have worked with Dekra testing a wide variety of materials. Aluminium foil is not a material used in product design nor is it structural or impact absorbing.
Polycarbonate has been the common plastic used in the electronics industry due to its flexibility and impact resistance. That’s probably why riot police use it in there shields to which it doesn’t have to be very thick at all.
