Very strong!  Sorry -- I couldn't say how much stronger.  Just: wow -- that's a serious piece of FRP.

  If you're going to layer it by hand with epoxy, you might want the outer surfaces to be glass or a glass-carbon hybrid so that you can be sure they are entirely wet out.  If you're not infusing, the wetting-out of carbon and kevlar can be very difficult to determine.    You'll also be able to sand/fair it a bit more easily in that you can eat into the glass slightly and still get a nice finish.
