Hi,

Lexan is not brittle at all.

Thick lexan is used for bulletproof enclosures...most gas stations in
and around downtown Houston have 1" thick lexan boxes around the
store clerk. 

I have shot 1/2" lexan with a .22 rifle - instead of shattering, the
bullet just sticks in the plastic. Amazing stuff.

A good test to discern between plexiglass or lexan, is to break off a
small piece and use epoxy on it. After a day or two, epoxy will break
loose from plexiglass. 

I had a primary coil once, where I epoxied lexan supports onto a
plexiglass baseplate. After a couple of weeks, the entire primary
coil - supports and all - became separated. It was pretty funny.

Anyhow, epoxy will never come off of lexan after it has hardened.
Makes things very strong, maybe even bulletproof!

Take care,
