So I’ve always been under the impression that the North Machine is made out of carbon fiber. Today while packing my gear up, I noticed that some of the carbon fiber chipped of revealing a metallic interior of the tool...
So my question is, is the extremely thin layer of carbon fiber just a facade for the tool? Or is it actually functional?
My understanding is that the carbon fiber reinforced composite is wrapped around an aluminum substrate. The shaft is not entirely made of carbon fiber composite material. It is more than facade, as my experience has been that the Grivel “carbon fiber” tools are slightly lighter, damper and less thermally conductive than their pure aluminum counterparts.
IMO, the difference is not as significant as the BD cobra, which I believe is a pure polymer matrix composite,
