Afaik, fatigue limit just doesn't apply to carbon fiber since it's a metallurgic term. So not having a fatigue limit means something completely different than with alumin(i)um.
Carbon fiber can take an infinite amount of repeated stress as long as it doesn't exceed the stress limit. Now the resin can deteriorate but that's a much slower process than metal fatigue afaik.
