What material are airplane windows made of?

What material is used for airplane windows? Here I am referring in particular to passenger airplanes. They have to stand a lot at the front of the cockpit. And also the small windows where the passengers sit, what are they made of? Does anyone know a precise explanation? including a description of the material or a link?

  1. Windscreens
    Windshields depend in their nature and in their structure on which aircraft they are to be used. In particular, it is decisive here what possible impact forces must be taken without damage (e.g. hail, bird impact) and whether the panes should be electrically removed or not. Electrically heated discs are used mainly in aircraft with a pressure cabin to remove ice and moisture fitting. The heating of the glass also increases its resistance to impact forces (hail, bird impact).
    The panes have a layer structure of “tempered” crystal glass combined with plastic layers.
    (“tempering” = hardening by cooling)
    “Polyvinyl Butyral” is used as plastic. Under pressure and heat, these layers (all glass and plastic layers) are bonded together without the use of any binder. The physical properties of the vinyl layer are strongly dependent on temperature. Under normal operating conditions, the plastic, depending on the temperature, can be very fragile (low temperatures) or plastic (high temperatures). For this reason, the resistance of the disk (in the overall structure) to impact forces depends on the temperature which the vinyl layer has. The front panes consist of a specially laminated construction, embedded therein a heating element consisting either of a wire insert or of vapor-deposited layers of gold or tin oxide on the inside of the outer pane.

It should consist of special polycarbonate (macrolon). Normal glass would inevitably break in the expansions and stresses that take place in aircraft operation.

Materials for aircraft should have as great a structural strength as possible so that the weight of the aircraft can be kept as small as possible. In principle, steels, light metals, wood, paper, fabrics and plastics are particularly suitable for aircraft construction. Whereas wood has been used in a meaningful manner up to medium sizes, the metal and composite construction in aircraft construction, in which various materials are combined in such a way that their properties are each optimized, is preferred.

great, but unfortunately nothing to the question!

I would think macrolon,that is a plastic,so discs are used in motorsports on any occasion
