How does a windshield perform in an accident?
The windshield must break. When the windshield breaks, the glass must remain stuck to the pvb to minimize any cuts that would occur if an occupant were to come in contact with the windshield. The windshield must be able to stretch while absorbing the energy of the crash. This is why a soft flexible plastic layer is sandwiched between the two pieces of glass. The windshield must also keep you in the car during the entire accident. A windshield should not allow your head to penetrate through the glass. Finally, the windshield must remain attached to the vehicle opening. Windshields play a significant role and are very important for both frontal impact and rollover crashes.
