Are these terminals made of tinned copper?

Yes, they are made of tinned copper and thick enough to do job. It also uses polyolefin, double wall, adhesive lined tubing.

Is there ribbs on the inside of the barrel or is it smooth?

They are smooth. There's a tab on the inside to stop the wire from going all the way through. If crimped right and heat shrunk they won't pull apart
