A caixa de Ype me deu confiança para comentar em português: Achei muito legal o video, gostaria que postasse uma narrativa. Deixe indicado de onde vocês são, qual empresa, etc, tenho certeza que será util para aqueles que procuram coisas tão específicas no RU-vid. Bom trabalho!
Hi, This is a really nice and informative video to get an insight of the manufacturing. Never the less, as someone who also works with composites, you should do yourself a favour and and wear gloves during any lamination process! Any kind of resin is really unhealthy/toxic when you get skin contact with it. Also not all kinds of gloves are good for a resin protection. Gloves out of Nitril should work fine. Anyways... Again: Nice work and nice video! Best regards
Achei estranho uma coisa, em planadores de competição, as metades das asas (superiora e inferiora) são unidas DENTRO de um molde, sob pressão e normalmente, com sistema de vaccumforming. Nesse video, metade do revestimento foi colada sem uso de molde. Isso faz muita diferença?
how did you make the mold and what is the mold made out of. I am guessing maybe an equation driven curve in solid works but where do you even get a CNC machine that will cover that big of a space?
Hello Ron! The mold we used fiber glass fabric(20 layers) at that time we didn't use CNC, instead we used a original broked wing, but now we have a CNC with 5mtrs long 2mtrs wide and 1,5 meters tall
Hello ! it is awesome video i am wondering about the thickness skin of this AEROBATIC CARBON WING in inches and does it really resist and sustain very high pressure at high altitude
After working at Gulfstream for over 18yrs and with carbon fiber lay ups....... I can tell you that we never did a lay up without white, lint free gloves on because of the oils in your skin
That's the difference between manufacturing a certified aircraft and an experimental - relaxation of process. I would use gloves whatever composite system I am using. Proper air extraction and a clean room environment are also key H&S aspects, even if the work is Experimental.
Hi Claudio, can you manufacture a laser 2300 wing? I have the original plans for a wood wing but I'm looking for a carbon fiber one, edge540 or Zivko wings are the time of wing. Regards
i dont know a single composite GA aircraft that its not glued. in fact, even non-FA are glued too. i cant imagine making a wing with a mouldless AFP or winding.
@@pedrobalduci7754 i should specify, secondary bonding or co-bonding is a challenge, it means a cured part bonded to a non-cured. The quality and therefore reliability of cohesion is more difficult to achieve then for co-cured structures, where parts are cured together wet on wet, or in a one shot infusion process as for dry fiber textiles. For example large commercial aircraft where parts are made of composite, are riveted for the exact same reason. I should say that for a small aerobatic aircraft, the build process is sufficient, if properly executed.
@@servanttofriend8481 It is the challenge of co-bonded structures, means one part cured to a non-cured part. A good bond quality is more difficult to achieve.
this video could have been very informative if you would have told about the materials as you put them together, i have hand laid many 18,19,and 21 foot boats with fiberglass and i also build and fly r/c aircraft and was thinking about carbon fiber, but i still don't know much about it sense watching your video
some steps not clear, I am wondering how the upper and lower surface are joint together and without any wreck looking at all? I didn't see any steps working on that, can anybody help to explain? Thanks.
Dear sir, it's wonderful job. I have experience also in composite and uav manufacturing. I want to ask can't u give me a job in your company. It's very important for me. I have 12years experience in air frame but military. In addition to I am from Sri Lanka. Can u pls help me sir. I would like to serve your company as well as I can. Thank you.
Regis, a técnica do BIQUET, termo Francês, se lamina uma faixa em tecido(carbono) ao longo do bordo de ataque , metade da largura é colada pela parte interna, deixe secar, depois quando juntar na hora de fechar, a metade que não foi colada, ira se juntar e ficara reforçada esta parte
i'm assuming this isn't a wet wing. its weird to work with carbon fiber especially when you have to trust your live with resin, glue and carbon sheets instead of bolts, rivets and metal. i'll never get used to it, even the costruction is completely different
They carry fuel in the wings as well as inboard I'm not sure if there's a liner but an all carbon MXS is G rated to +/- 14 g and an aluminum RV-7 is at +6/-3 both at 1600 lbs acro weight
Aluminum inevitably fails at imperceptibly small cyclic loads. No matter how strong an aluminum airplane is made, it will disintegrate in midair if it's flow enough hours. Competition Aerobatic aircraft are almost never made of aluminum. Steel tube fuselage, composite wings and tail surfaces. Or all composite with a strong fuselage that can sustain 25-40gs for crash protection.
It's probably resin filled with glass microballoons, it's commonly used as a glue for such constructions. I'm glad I can answer Your question after 3 years of You asking it.
no....I'm going to build one from scratch using a 3D printer! I just have to make sure that I build a engine nacelles capable enough of withstanding and containing a catastrophic failure just incase the compressor disintegrates at high rpm due to the extreme temperatures.
Hi Claudio. Thanks for posting this video! For what airplane is this wing? I don't recognize either the red material or the white material you are spreading. Can you tell us what those are? Thank you!
+voronwae Thank you for your response, Claudio! I don't quite understand your answer. Can you tell me the company names for the red and white materials? Also, what airplane are you building? Thank you again!
@@generalrodcocker1018 These guys do not appear to be using prepreg which is fabric that comes with the epoxy already impregnated in the fabric and requires heat to cure. Other, two part epoxies do not require heat, because you mix the curing agent (hardener) in with the epoxy before putting it on they fabric like they did. This looks like a small shop building a prototype and they likely don’t have the hundreds of thousands of dollars required for a giant autoclave. I worked in a very small shop doing this very thing once, and we never used prepreg.
i don't know one single general aviation company that actually uses autoclaves to manufacture their products. they normally use ovens (aka post curing rooms) and vacuum systems
But what could you do with the same technology but getting a little more creative in the thinking of the overall aircraft design, I mean please, we are in the 21st century with carbon fiber technology, CNC machining and computer science and all we can come up with is a 1940s design aircraft, I personally would like to build a carbon fiber aircraft powered by a 1000cc turbo charged engine and twin 4ft variable pitch unducted fan units similar to NASA's high efficiency unducted pro fan, and for once and all take away the prop speed record held since the 40s by the P51 mustang, I mean please, what a joke
Some friggin explanation of what the hell they're doing and some details. I didn't learn not one single thing from this video. Was it supposed to be instructional, or just showing off. You might know how to make an airplane wing, but you can't make a video worth a damn!
