Carbon question

[Lee]

I have a little project in mind for the winter.

i am considering having a diff housing in carbon , the only query i have is, can you fix a piece of carbon at 90 degrees to another piece of flat carbon, ie can you drill and screw into the vertical piece of carbon without it de-laminating.
If there is no way then i will just have alloy blocks made up and use these as mounts for the carbon to be attached too but i thought it would just look cleaner all carbon.
