One thing I have always thought might work, but have never tried it is to get some super glue remover or denatured alcohol, remove the nock, position the arrow so the insert in down and the nock end is up, and pour it down into the arrow from the nock end. Maybe let it set for an hour or so and then see if that has loosened it up at all. The downside could be though that the chemical might weaken the carbon down around the insert after working on it like that. Might be worth a try...
I wouldn't try this. If it desolves the super glue, it'll weaken the carbon bond and you may have an arrow blow up on you unexpectedly. (See below)
Maybe, but I really doubt it; and the reason why I say that is that they make high end rifle cleaning rods out of carbon fiber now. Gun solvents are just as bad, if not worse than those chemicals I mentioned with the penetrating properties many of them have. The pressure I have to extert to get a jag down through a barrel is pretty great and I have never broken one - even after that rod has been subjected to gallons of some of the most caustic stuff you can find. I use denatured alcohol all the time to clean my arrows on the outside and have never noticed any degredation.
Nonetheless, weakening the arrow down next to the insert would not cause an arrow to break in the middle like that in the posted picture. The oscillation and flexing during the shot broke it at the point of maximum flex (middle of the arrow) probably due to previous damage. That's why we always say "Flex it First".
