HONEYCOMB PANELS IN AIRCRAFT INTERIORS - The magic behind lightweight and strong construction

[@redionlamaj]

this was a great video explaining a great deal for this panels! thank you for making this video!

[@D4ftd0g72]

These are the same panels used in over head projectors in schools in uk. We have loads of them left over after have new flat screen tvs. Your video has kept me up all night dreaming of what I can do with them! Thank you.

[@planesimple8514]

Cool! It's great to have access to panels like that. There's A LOT of people here that wish they could get their hands on some of those. Have fun making stuff.

[@Geekchica]

Sir, thank you for the introductory look at how to affix the threaded inserts and sleeves into this material. Do you have a video on how to join two edges of the honeycomb - as in construction of the drawer "box" shown at the beginning of the video? The box/drawer does not seem to be joined using the assembly pins - unless the pins are covered up in some way after they are installed. During the video you describe how an assembly could be done with a butt joint, but I don't know if that pin assembly is used for a ninety-degree mitered joint.

[@johnwoodriffe7465]

Thanks, very intresting. In an airoplane, not all panels are is flat, how are the curved panels in multiple directions acheaved being light and strong

Hello, we are the honeycomb board manufacturer, so nice to see your video! I hope more and more people could realize the advantage of honeycomb board as cabinet material rather than the stainless steel :-)

[@planesimple8514]

Hello JIAWAH, and welcome to Plane Simple. I'm honored to have a manufacturer like you take the time to write in the comments. I think that more people would use the material if it was readily available. It has traditionally been very expensive and therefore reserved for high end industrial uses and out of reach of the common people. If it was made more available and affordable, it would only be a matter of time for the product to explode in popularity and adoption. Even in this comments section there are several people that I'm sure would love to get their hands on some honeycomb panels. Thanks again for writing in.

Thank you so much for making this, Ive bern wondering how inserts were installed.

[@ThatGuysProject]

Would it be stronger to directly bond two sandwich panels together or use inserts and bolts? For example a wing structure or torsion box? I suspect a direct bond would be stronger however harder to deal with if you had to do maintenance.

[@Wohambi]

Hello and thank you for this video. Are there any downsides of applying honeycombs in compare with foams for example?

[@planesimple8514]

Hello Wohambi, that is a highly technical and specific question that requires in-depth knowledge in the subject. Far more than I have. Therefore I can't even begin to answer your question, because I can't. I'm sure the application dictates the choice of core material, skin material, and the thickness of each, but as to which to use when... I don't know. Engineers determine that. On the other hand, if you know the loads and environment of your application, you can read the specs for different materials and pick the cheapest one that still suits the need. I know this answer is not what you were looking for, but it's all I can give. Thanks for coming by Plane Simple.

[@TheSilverSurfisher]

Greetings, thanks for the informative outstanding video. Where do I find the pins (epoxy injected pins) that are used to secure the carbonate or honey comb material?

Great video! I'm looking to buy this type of honeycomb sandwich panel for an aircraft interior project. Could you recommend suppliers or companies that sell this material? Thank you!

[@planesimple8514]

I know AAR composites was one, but they may sell through other distributors. Also, if you scroll down through the comments on this video, I believe there was a comment written by an actual honeycomb sandwich panel manufacturer. You can contact them. Good luck on your project

[@damonreynolds110]

Hey everyone, so I have a load of used aircraft floor boards that I pulled from a skip before I left my job in an aircraft maintenance facility in February. Planning to make cabinets for a campervan out of them but I have I cannot find a supply of the pins for joining the panels with resin. If I can't find any I might have to make my own but Id rather it didn't come to that. Does anyone know any other names for them? Or even better, part numbers? Any help would be appreciated

[@planesimple8514]

Hello Damon Reynolds, you have an uphill battle ahead of you. The pins are called ATR panel pins or tie pins and they come in specific sizes to fit specific panel thickness es. The epoxies we use are ATR525 from AAR Composites or DP460 from 3M. The reason I say an uphill battle is because these parts are very expensive. Their cost is justified in an aircraft, but for any home, DIY use they are ridiculous prices. Another method you can try is using counter sink or flat head screws instead of the panel pins. I don't mean to thread the screws into the panels(it won't hold), I mean to substitute the pins with the screws and install them in a similar manner. Drill a hole the size of the screw(the thread diameter, not the head diameter) in the panels you want to join, pre fill the hole with the epoxy and "nail" the panels together with the screw while the epoxy is still wet. Clamp or tape or secure the panels in place and let cure. The treads of the screw will act as the knurls in the pins and the head of the screw will act as the flare of the pins. It's not ideal but a helluva lot cheaper. As for the epoxy... I don't know of a cheaper alternative. I'd do some searching for a cheap epoxy that cures solid that bonds to both metal and carbon. And speaking of carbon, most floorboards are made of carbon fiber. When you cut, trim, drill or sand them, don't breathe the black dust. Good luck.

[@donjayamaha6174]

Hi I have seen ultralight aircrafts builders use sandwich panals for wing ribs can you use the inserts you showed to attach ribs to the spar or is it something you shouldn't do

[@chuckvivian4711]

Thanks for this expiation. Way Cool!! Where can I buy those little epoxy pins? What are they called?

[@planesimple8514]

Hello Chuck Vivian, those "epoxy pins" to join the honeycomb panels are literally called panel pins. Try googling "honeycomb panel pins" and you'll see a few results of companies that sell them along with theater inserts and such. One of them is called TYE-The Young Engineers, they have anything you can imagine for honeycomb panels but it's intended for aviation so expect the prices to be way high! Maybe McMaster Carr would have them too... Good luck.

[@trevork6219]

Well explained. Thanks for sharing. Furniture for frail or old people could be made light (movable ) and strong (fall protection) using these methods and materials.

Very true. One of the very many applications that would benefit from such materials.

[@planfubar1749]

Great video sir! I am restoring and old Airstream Camper and would like to build the interior with honeycombs panels like aircraft. I am having an extremely hard time finding resources on construction techniques as well as material suppliers. Do you know of any books or white papers on construction techniques and any suppliers? Richard

[@planesimple8514]

Hello Richard, thank you for your kind comment. Your airstream restoration sounds like an amazing project. Sadly, I've never tried buying honeycomb sandwich panels for myself, it's always been for work which is aircraft interiors. And like anything aircraft, it's expensive. Just off the top of my head I think a good ballpark price for a fiberglass skinned 4'x8' sheet is around $400. Prices will also change for aluminum, carbon or Kevlar, etc. One supplier I can remember is AAR composites. However, there must be other suppliers and ideally non-aviation suppliers should be less expensive, sadly I don't know of any. I will do some googling and if I find something I'll add to this comment. As far as building techniques go, I could offer a bit of info but not much more that what's already on the video. Anyway, sorry I wasn't more helpful but I wish you the best of luck with your airstream.

[@bighardtop]

I've often wondered why RV and camper manufacturers don't use honeycomb panels instead of that cheap fiber board they use. This would be lighter in weight and much sturdier. I would interested to see how your project comes out when finished.

[@christianback4256]

@@bighardtop Actually Safari Condo, a Quebec-based company, has built its entire camper trailer line (Alto trailers) around this technology. They are the lightest on the market for their size. They are costly but keep their value because they are impervious to rot, rust, etc. The main disadvantage is that the shell has almost no insulation. We have been using an Alto trailer since 2016, and overall we are very satisfied.

[@polymerx2218]

Where did you buy the hollow knurled joining pins/dowels? Thanks

[@planesimple8514]

You can find them online from several aviation parts distributors. Just Google "ATR Panel Pins" and you'll find them. Read up on them, they are color coded for each pin diameter to match the panel width they are getting installed into.

I built NASCAR Truck Series race cars(trucks), we used these panels to cover the pickup truck beds, we used 1/8” panels and the skin was titanium, it was all about weight and strength. Rotor Broach - if you drill a pilot hole a little smaller diameter than the spring pin, just so the tapper tip centers, when the cutter cuts out the plug, the spring loaded pin will eject the plug and the plug will not have to be dug out of the cutter.

[@planesimple8514]

Just found your channel and quite enjoyed the content! For the home enthusiast I think you could use a woodruff cutter or a t-slot cutter for the relief around the insert. An alternative to the expensive and hard to source sandwich panel inserts could be Chicago screws or something called a sex bolt. Grind or file flats on the base to help provide mechanical attachment to prevent spinning. From a 30 year veteran Aerospace worker thanks!!

Infusion i'd guess. Ask google.

[@martynaskirsis4179]

Definitely not infused. Its made of prepreg fabrics and honeycomb under pressure. Press maschined or in autoclave. You can make your own sandwich panels making skin's separately then bond them together with honeycomb with thin layer adhesion paste. Pressing under vacuum or simply load some weight.

[@planesimple8514]

Hello MJ Remy, thanks for your kind words and for keeping it respectful. I apologize for the crappy audio. I am not a pro at this, as it is painfully obvious. I do not own a lapel mic. On top of that, most of the videos I do are at work, surrounded by electrical rooms buzzing, noisy lights, echo-y hangars, running engines, etc, etc, so the background noise is always terrible and always there. I rarely get the chance to plan or script a video. They mostly happen spontaneously whenever the opportunity presents itself, I just whip my phone out and start recording. I know the end result shows every bit of those defects. As far as the video dragging on, that's the result of not pre-scripting it and just letting my brain ramble on on the fly. Sorry about that, thank you for your patience and for putting up with it.

[@planesimple8514]

Those panels are amazingly strong for their weight. The thicker the core the stronger the panel will be. When you find a panel distributor, they can give you spec sheets for each panel size. That way you can select the size panel you need for your application.
