I wonder how long the carbon fiber cable lasts? We've got 100+ years of experience with steel cabling, I wonder how carbon fiber compares. When it fails, it'll probably be by snapping. I hope there's lots of redundancy in place!
- Ekaros 3y agoMultiple cables always. And it is basically epoxy coated flat piece. So I don't think failure model is that bad.
- drtgh 3y agoUnlike steel, there is a point at which carbon fiber will suddenly break like if it were glass, and this will happen without external warnings (micro-fractures non visible to human eyes). In the video one can see in the cable what apparently seems to be metallic layers for this reason. Epoxy would only increase the stiffness and therefore the brittleness. It is not my field, mere layman point of view then, but I can imagine that the revision of these cables would have to be based on ultrasonic or microscopic scanning to detect such unpredictable micro-fractures. I'm not sure if this cable would be suitable for a place with earthquakes or high winds.
