PLA-CF is not particularly stronger than PLA. Some properties are improved, mostly geometric stability and appearance, but the carbon fiber acts more like defects in the plastic than strengthening. It’s got very little of the benefits that you’d imagine based upon n experience with regular carbon fiber.

This. CF rarely makes a print stronger, usually just helps make some materials more forgiving to print. Particularly useful for warping prone ones.
