My theory for despawning fragments is that if you have already unlocked the blueprints for that object, any new wrecks that you have not previously-loaded into memory (i.e. visited the region close enough to have the wreck spawn in at least once) will no longer have fragments for that blueprint. There do seem to be some exceptions that always spawn (e.g. propulsion cannon fragments).

I could spend a couple of hours testing this, but it would save me some time if you already know the answer to that.
