Are you on PC or console? The Research option doesn't disappear, but if you continue to give her discs after everything is unlocked, she will take 10 discs and give you a book you can use to upgrade the output of your factory. Also, not all tier 1 and 2 items are "visible" from the start.

Also, if you - like me - are running on an old savegame where everything was unlocked, and have begun playing again, the new 5 disc item might be the Forge. It was added in the last patch.

AFAIK, you can't break anything giving discs to Petra, the worst outcome is that she'll just give you one of the books I mentioned. And you can upgrade the factory with more than 10 of these.
