lol @ Hardmill..
I looked over the data...it has CF and other fibers in it..this will kill your EM's fast. Keep tools sharp, and use alot of coolant to keep it cool...use a International Minicut rougher and real good carbide endmills(TiN coating a minimum). It also will likeley chip easily, so mill pocket in(start from the outside and work your way to the inside of the part)..this will stop pieces from chipping off and damaging the part before it is finished..
