Hmm. It is not difficult to imagine that not only are geodesics and CFRP similar, for purposes of discussion here, they are identical.

Strength/Weight was always a driver in Aviation, hence Spruce rather than Fir, and Titanium rather than Steel. When the paradigm became Moot, we went back to solids. Howard Hughes developed an early form of prepreg using Birch veneer and Urea or Phenolic shear layers, enormously strong, and absent the need to "relieve" structure to minimum weight to maintain Strength.

The "Skeleton" of steel tube covered with fabric became obsolete when prestressed Aluminum panels and minimal structure could provide a three dimensional operant of what the Tube Fabric structure only "suggested".

Inside every solid and shaped prepreg panel of Carbon reinforced Plastic is a ghost of the Honeycomb, and the "Geodesic".

The secret to strength has always been "Two Phase", being a matrix enveloped in some solid. Bamboo is a perfect analogue in Nature of Rutan's best efforts.

eg: Fibrous/Lignin and Carbon Fibre/Resin. Same-o same-o.
