What type of polymer is used in the windshield of airplanes?

The airplane is encountering quite a force when flying.

Polymer is used because it is extremely strong. It will try to "absorb" an impact rather than just break into little pieces.

A windshield/window of an airplane is designed to withstand the actual impact of even largish birds.

At some time they did indeed test windshields/windows for planes with something commonly known as a Chicken Gun.

In the early days there was a person who smashed one windscreen after another and he could not understand why because they should withstand it.

After a while somebody asked him if he had defrosted the chicken first. Ooops.

The windscreens on airplanes are not tough enough to withstand frozen solid birds.
