You can drill fiberglass. The strength after you put a hole in it depends on lots of things..but a 1/2" rod with a 1/8" hole should still be plenty strong.

Beware of safety issues, use eye protection, a dust mask, and a vacuum. If you need to saw the material a normal saw blade will work, but will dull quickly. If you need to make a lot of cuts then try to use an abrasive blade, such as designed for cutting masonry.
