Hi Guys, I just scored a fair amount of 1/8" thick Nomex honeycomb, much more then I will be able to use. I can make up just about any composite panel with the stuff such as balsa, glass, CF or 1/64 ply. I was thinking that it's a great material to make bulkheads, battery trays, servo trays and such. I have used it in the past as tail sections on a few airplanes after bagging it between a couple sheets of 1/16 balsa. Question is, would there be any interest in honeycomb panels that can be fabricated with whatever skin you would want? Obviously prices would be dependent on the material used.

Shaun,

I think you may have a bit more response from the Jets jocks.

Would you be able to post overseas?

Matt K, right now i thing honeycomb in the jet forum is a nasty word LOL. It seems a jet manufacturer is using it incorrectly with disastrous results. I have seen lots of pictures of pattern airplanes with composite formers and trays so thought it would be of some use here. IMO a plate of this honeycomb with 1/16 balsa on both sides that has been bagged then sanded so the balsa is really about .040 thick and then bagged again with 1.5 oz cloth that has a peel ply finish would make very strong and light parts.

Matt13 I'm sure we could work something out on shipping.

I don't usually follow jet activity. But I just happened to see where someone was talking about carbon and ply laminates for certain things. Looked like way overkill for the task so I thot of your post

Matt, have you seen some of those guys fly? LOL I know I'm going to get it for that remark. Oh well.

I was at Sepulveda Basin one time and watched Jim Oddino flying some FAI manuvers as well as he is capable of doing, and I think I was the only one watching. Then some guy taxis out a jet, takes off, goes whoosh across the runaway, climbs out. . . whoosh the other way. This went on for five minutes then he manages to plant the thing back on the runway, only bouncing twice, and everyone aplauded.

Instant talent, just add kerosine.

Yes I have....VERY UNIMPRESSED. Once you get used to the speed, you gotter licked. BIG WOOP!!

Now, the rather recent development of Jet Precision Aerobatics is something worth noting. High drag, high aerobatic capability airframes being flown at near constant speed. Jet engines of course. This has much muchmuch more appeal to me than getting from point 1 to 2 in a few milliseconds. But that may be getting too far away from your original intent for this thread especially the yelling

I would think that Fly Eagle Jets would be interested. Sorry couldn't resist.

LOL Rapture, I have seen pics of their usage of honeycomb and they have no clue how to use it properly. The failed stabs I saw had the honeycomb used as spars with the cell orientation being horizontal. If that wasn't bad enough they simply capped the main spar with about 2 square inches of 5.7 oz CF and then bolted the pivot mechanism to it. The sad thing is that some owners of these jets still think that FEJ can send them some scraps of material along with instructions and it's all fixed.

Anyways, back to the post topic. Obviously this is not a real money maker here but I hate to see this material just sit around. I also just got a lifetime supply of Cabosil so I can supply that need as well.

Speedy,
Are you willing to sell small sheets of the honeycomb as-is? I wouldn't mind having some around the shop.
What's Cabosil?
Dan

Sure, I would be happy to sell as is. Just tell me how much you want and I will PM a price. Cabosil is the powder that is mixed into epoxy resin to thicken it and keep from having the epoxy flow out of joints. Very handy to have.

Cabosil,,,fumed silica.... in the production of optical fiber for example, pure silica is vaporized to make fumed silica preforms. These are carefully melted and drawn to make a variety of optical fibers.

When the process doesn't go well, bunches of extremely lightweight fumed silica are left over. Turns out this stuff is incredible thickening stock for epoxy and adds virtually no weight. But adds practically no strength either, in the manner glass or carbon fibers do

what is the cell size and density of the core?

you said 1/4 or 1/8 inch thick?
