But, separated by a very large piece of conductive metal. (I think even carbon fiber planes have a conductive layer in there, to prevent damage from lightning strikes.)
- skykooler 3y agoIsn’t carbon fiber conductive itself?
- tonyarkles 3y agoCarbon fibre is definitely conductive. A couple of years ago I measured a 1” diameter tube and got about 15ohms/ft.
- Animats 3y agoRight, it's a resistor. This is a problem for airframes and wind turbine blades. Its resistance is too high to deal well with lightning. So aluminum is needed to provide a conductive path.
- thenickdude 3y agoYes, and blocks radio transmissions very nicely. When making a model airplane with a carbon fibre hull, we have to add a plain fibreglass or plastic window for the antenna to receive through.
