The engineering data is free for the asking from the weaver/manufacturer. It's water migration properties are similar to glass.It appears that this material has been available for the better part of a decade - so why haven't I heard of it before and why is the engineering related data apparently so hard to find?
Seems like it might have some applications for us if treated the same as Kevlar with respect to H2O migration?
With zero weight, it would only need enough wing to carry the payload. So you'd still have wing loading.Really?
I thought you would need some weight. Wing loading and all that. Otherwise your plane would be tossed around by the slightest breeze, like a tissue in a tornado.
I thought this thread was initially about weight distribution, not wing loading. Maybe the ideal weight of the airframe and engine would be zero, but in order to fly you still need some mass from the payload.With zero weight, it would only need enough wing to carry the payload. So you'd still have wing loading.
If you had zero payload, it would all be rather pointless...
BioMid fiber is a crystalline cellulose fiber. It is not the hollow tubules of cellulose that a tree naturally grows; rather, it is an 11 micron solid fiber of a material that is "insoluble in water, ethanol, ether and dilute mineral acids." (https://pubchem.ncbi.nlm.nih.gov/compound/cellulose) It does not "absorb more resin" than glass. The finished product weight is determined by the rule of mixtures, just the same as any other fiber/resin matrix composite.D, Sounds too good to be true, but if it's cellulose based, it may absorb more Resin than Glass or Carbon. The product may be lighter but the finished product may be heavier. What is Crystalline Cellulose and how stiff is it to Carbon?
I buy individual 100 yd. rolls wholesale directly from Absecon Mills. I can supply you with a smaller quantity if you’d like to try some.Who is/was your supplier? Will they sell to anyone smaller than a medium sized government? Is it still being made in fabric form?
They should probably think about getting a new marketing department, it shouldn't be this difficult to find.
Maybe, but, the strength to weight ratio of a composite material is strongly tied to the length of the fibers and how tightly those fibers a bound together in the matrix. Paper is composed of very short fibers with little or no matrix. This is not a recipe for a strong and stiff material so to make strong structures out of it you'll have to use a lot which means that structures made from paper will be heavy. Adding a matrix (glue) will improve the strength and stiffness quite a bit but it's still not anywhere close to the most similar composite, which is wood. Think about it, paper is simply chopped up wood that was floated in water and lifted out with a screen to make a thin sheet. What used to be long fibers are now short and the once continuous matrix has been broken up into a bunch disconnected chunks. Restoring the matrix by saturating the paper with glue only dose part (a small fraction actually) of the job of restoring the strength of the original wood because the fibers are short and not all oriented in the same direction (in a wooden part all the fibers are parallel and extend the the whole length of the board). In long parts like spars it's essential to have long fibers (preferably the entire length of the spar) because the matrix is not as good as the fibers in either tension or compression.Would a real aircraft (no scale model) be able to fly if its wings were made out of paper?
