There probably isn't a cap, it is just diminishing returns. If you put on one armor piece at a time, you will see it doesn't add up to what it should for just those pieces. In fact even a single piece suffers from diminished returns for some reason. I used 2 of those 10% pieces and got 16%, not 20%.
The simple answer is, you can't just add up your resistances and get the right answer.
any items which effect the same atribute on a ship will cause a diminishing return. done deliberatly to ensure there no chance of someone ever becomming near immune to a weapon type.
same with consoles that increase weapon damage as if everythin stacked perfectly then at high levels weapons would be doing insane damage.
