Greetings
At the moment I am still completing the 90% complete, 90% to go stock KR-2
project that I am hoping to finish in the next year to 18 months and then
get airborne.
The question I asked was more of a theoretical one for a future planned
project after this one and because finding some of the materials taken for
granted elsewhere in the world has been a challenge here. I have spoken to
a few local suppliers while running around buying bits & pieces and the
response has been positive and most have stated that PVC or XPS similar
laminates would be stronger and lighter than the equivalent marine-ply
although their experience is in general construction or boat repair and not
aircraft construction. I am trying to find the article where one
manufacturer went as far as to say that their structural XPS or PVC is 24%
lighter for the same comparable strength than plywood.
They are also non-flame spreading (ie will melt and might burn in a fire
but will not propagate a fire) and will not create burning blobs or noxious
fumes like standard polystyrene.
This all said, I am still far from finding a perfect alternative and seeing
some of the other discussions, I am not the only one :)
