Where are you getting your information from on the use of cardboard in the use of aircraft???
In all my years in the US Air Force working on B-1 Lancers, and working on commercial aircraft as a licensed FAA Airframe and Powerplant mechanic I
have never once seen or heard of cardboard being used in anything other than the cup you drink out of when the flight attendant is serving drinks.
However, as far as laminate go the strength comes from the composite fibers warp, if you use a warp clock and lay out fabic in 360 degrees you will
have on heck of a strong part... The matrix (aka hardner and catalyst) do not provide strength, it only keeps the layers together... As far as
honeycomb core goes most of which are usually made of out Aluminum, Aramid fiber, carbon fiber, fiber glass, high density foam, as well as phenolic
material as well as other exotic composite materials.... cardboard my friend just isnt one of them based mainly on the fact of its construction which
is similar to plywood or compressed wood, it has no warp, weft, or bias... there is no strength in any given direction in a given sheet. Only in the
honeycomb core can I can see strength but even if it were used in aircraft and I'm 99% sure that it is not it would never be used for anything
structural or in any area subject to tensil, shear, or other stresses..
I have been a aircraft mechanic for the better part of 15 years now and I've seen a lot of airframes and have not yet come across cardboard... If i'm
wrong please give me a source id love to know how they did it and where they use it. However if you cant stop scaring people who fly often and dont
know much about aviation... they dont need to know that on 95% of aircraft the only thing that holds the engines on are 2 or 3 1/2inch bolts and or a
few small clamps...
