A question about Chobham/Composite Armor

[pmulcahy11b]

I haven't been able to find an answer to this question (probably due to the classified nature of these armors).

It seems to me that the ceramic/honeycomb matrix part of Chobham would be sort of like a ceramic ballistic plate in Interceptor Body Armor -- it works because the plate spreads out the shock of the round's impact by shattering. You're not dead, but chances are that your ballistic plate is no longer as effective either.

Wouldn't that also happen to Chobham?
