Lexan windshield: Safe?
MY windshield is fubar and I need a new one. Looking at a nice fitting lexan replacement.
I don't care if it's legal or "Good for street use", I just want to know if it's safe.

Had a small crack back then, winter has made it a rather large crack.
I really don't want to pay for a new glass windshield... uhhg

Lexan scratches very easily. I've had 'safety' experience with lexan and glass. In a heavy crash, large chunks of sharp lexan fly about with much bigger potential for serious injury. However, I've never picked broken lexan from my underwear.

Lexan not for the street. Unless it's a dedicated race car and you are after the last lb in weight saving, I wouldn't use it on a track car either. As everyone else mentioned it, they scratch, flex, basically a PITA to deal with.
I believe regular glass ($200) will be cheaper than Lexan ($350) a few years back.

The main problem I see here is that the windscreen is bonded in and forms an integral part of the structure of the car - especially in a crash. For race cars with proper roll cages this is not an issue and the windscreen becomes just that - something to stop flies from splattering your helmet visor, but for a street car and for maximum rigidity in a crash the glass windscreen is a pretty important part.

All polycarbonates are very safe. That is what we use in the manufacture of BR (blast and bullet resistant) laminated glass. The outer layers are glass (no scratching / maring) but inner layers are laminated to polycarbonate layers with another medium ( PVB, SGP, EVA etc.). But for a single layer windshield up front? Naw. Besides, the real BR stuff runs about 25mm+ and up thick. GE does make a MR Lexan ( mar resistant) but has now where near the surface hardnerss of glass and it' way expensive. PPG aerospace division makes a lightweight poly for military etc. applications. A bunch of stuff you really didn't want to know. Sorry.

$650! yeow! There is a couple of places that specialize in dead / old new auto glass inventory. I'll ask an old csr guy that will know. Might be a link on the NGA (national glass assoc) webb site but like I said, I'll check it out see what I can find.
