A high percentage of the Carbon Fiber material is epoxy. The carbon fiber is more or less like rebar, in that it gives strength to the epoxy; I would guess that the carbon is no more than 50% of the material.
A lot of carbon fiber is created from cotton. Carbon usually falls into 4 distinct forms, diamond, graphite, graphene and buckminsterfullerene. Given the amount of impurities in these blades, I don't expect you are going to get much of a profit from grinding them up. Carbon is generally pretty plentiful, and about as precious as sand.
