The phenolic looks interesting as a motor casing. They spec axial tensile
strength but not radial. 60% the weight of aluminum but only 17% the
tensile strength. There goes the weight advantage unless one adds a carbon
fiber overwrap. And hydrostatic tests it. Still, there's the issue of
attaching closures to the tubing... appropriate adhesive, plus pinning,
plus insulation.

maybe of interest for airframes and solid motor builders-
championfiberglass.com
has glass epoxy and phenolic epoxy conduit in 3/3" to 8" sizes, three wall
thicknesses, 10 foot lengths
lots of coupling anf fitting options
even split clamp over repair/reinforcement tubes.
should be reasonable prices since its a commercial product.
