Are my hairline cracked or broken carbon fibre handlebars broken or useable?

Are my hairline cracked or broken carbon fibre handlebars broken or useable? Can they be easily repaired?
They came with a bike second hand. I didn't notice it till I took the bar tape off. I haven't ridden them.
It looks as though the broken and cracked areas may just be fairings that wouldn't affect structural strength but I don't know for sure. I have seen carbon bars that don't have this bit.
Can anyone shed any light on this? Can I do a strength test at home?

On the one hand, it really looks like it is only the cover where the cable passes under. On the other hand, I am not sure if it still could be a structural element which was designed to take some of the load. There are some people who fix carbon (at least frames), not sure if handlebars can also be repaired.

Personally I would not ride it. When the handlebar breaks you will go down. Hard. I'd be nervous using it even if it was fixed. Plus I read somewhere (not sure where, so might be one of them urban legends) that one should replace lightweight tuning carbon parts after so-and-so many years anyway.
