    Barnaby Wainfan had plans for something like that on the fmx5.

    Yeah. Don't think he started construction.
    Just wondering if any other airplanes have flown in the years since 1999. Or if homebuilders have tried it.

    I think FibreLam died for some reason as an aircraft construction material. Only heard of one successful completion, and that was a glider in Great Britain.

    Re: Fibrelam panel building

    The Volksplanes call for a fuel tank/forward fuselage top made up primarily of sheets of Alsynite polyester resin fiberglass panels, which only seem to be made in New Zealand today and we know know that the resin itself is susceptible to modern fuels. I suspect most builders today make up their own epoxy panels on a sheet of glass or waxed aluminum and still have to protect the tank from the fuel.

    If there were a readily-available and reasonably-affordable source for high-quality composite panels today there would be lots of potential applications to homebuilts like the Optimist that go together from precut sheets like a big balsa or paper model. Unfortunately, that just doesn't seem to be the case.

    The fuselage of the Streak Shadow was constructed of Fibrelam.

    I think the Fibrelam is cored like corrugated cardboard. I don't think homemade is practical.

    Actually they're honeycomb cored, made by Hexcel corp and used in a lot of areas

    Then if it is Hexcel honeycomb it is too expensive.
    Need an industrial corrugated core to be reasonably cheap like boxes. And corrugated folds nicely along the corrugations.

    This ThermHex honeycomb is apparently much cheaper than Hexcel

    Re: Fibrelam panel building

    Are you looking for a corrugated core (rather than foam core) in a pre-made laminated panel for a particular reason?
    If corrugation is a must, maybe an inexpensive thing to look at might be Coroplast (the corrugated plastic used for signs, etc). I don't know how well epoxy would bond to it.

    Re: Fibrelam panel building

    Most, if not all airliners, use floor panels made of fibrelam or equivalent.....I owe my life to the Shadow being made of fibrelam. I reduced one to small pieces and the hull stayed intact enough for me to survive.

    The plastic Coroplast isn't very structurally useful. It would be if made with FRP or aluminum face sheets.
    The right idea, wrong material.
