carbon pole repair?

Has anyone here tried using carbon fiber fabric and epoxy to repair a
carbon fiber pole? If yes, can you recommend the type of epoxy and the
fiber fabric? I broke 2 poles within the last 2 weeks rollerskiing ,
by getting the tip of a pole stuck in a gap between concrete slabs at
a bike path bridge. One of the poles was an Exel Black Feather, so I
am mildly annoyed. I was thinking to get a thin aluminum tube from
McMaster and using aluminum putty to glue the pieces together. May be
carbon fiber would be a more elegant way, but I have no experience
with carbon fiber. Don't want to spend $300 on a new pair of poles w/o
giving repair a try.
