Great job. What would be the max wing length using this tooling ? Thanks
@HawthornComposites 2 ай бұрын
There is not necessarily a limit on potential wing length. It really comes down to making sure you have the time to fully "wet-out" the composite fabric before it starts to gel. There are plenty of variables to play with to ensure success for much larger wings.

Certainly a fine example of low-pressure resin transfer molding (RTM). The mold seal design is very old technology prone to seal failure at intersections of flange planes much more consistent and repeatable mold seal interaction is available today especially if the cavity is to be at a negative pressure (vacuum) as compared to ambient. The use of aluminum tooling, epoxy resin, and methods shown are well suited for Aerospace profit margins and would be very challenging to compete in a higher volume application. Especially with the use of 3M 77 spray adhesive used as a tackifier holding the fiber and core components. So many molding applications failures witnessed over the last 40+ years are tracked back to the use of spray adhesive especially used as shown, not to mention the added mold surface scumming. All and all, an excellent example of what can be done with low-pressure forms of RTM. Today the majority of parts are produced using variations of RTM, such as LRTM and most recently SRTM

You could just use prepreg and not do an infusion and it there would be less steps. Also consolidation in the transitions from web to skin could be controlled a bit more maybe. The smart tool is the secret. 150+psi will be magic. Ive made silicone intensifier parts where the layup looks like trash but, the final part is impeccable. Prepregs may have some issues but, seems much more reliable than sucking/blowing hot resin into a super heavy tank of a mold inside a 200+C oven. 😅😅😅

I thought the advantage of prepreg is the lack of air bubbles because of the very short path out of the material. I wonder if one could impregnate the sheets and directly afterwards lay up wet sheets in those smart tools. In a cold room.
@bradster1708 3 жыл бұрын
In this technique the resin is drawn into the carbon under vacuum inside an oven. The chances of air bubbles is small. This technique also does not require use of an autoclave oven. Boeing uses a sort of similar process in Australia making 787 parts with good success after a slow start.
@ArneChristianRosenfeldt 3 жыл бұрын
@@bradster1708 now I wonder how resin behaves when I send it through a heated nozzle ( 3d printer, or due to friction ) into vacuum. Does it evaporate? Below some pressure a lot of materials are either solid or gaseous. Chemical Vapor Deposition. Then as the pressure due to the resin itself rises, the new resin going through the nozzle stays liquid.
@HawthornComposites 2 жыл бұрын
Because the polymer tools can apply pressure both during infusion and cure, any air is driven out of the curing composite. This solution deploys automated carbon fiber sleevings and isotropic broad good to eliminate most of the labor that would be associated with applying carbon fiber prepreg.

Well, next time I have a 10 billion dollar defense contract come across my table I'll keep you guys in mind. Oh, it might be on your site but it might have been nice to see how scalable and modular this process is. I can imagine those molds and "smart tools" as well as the resin impregnation process facing increasing difficulty and variability as they scale up.
@diviscadilek1764 3 жыл бұрын
I don't know about difficulty. Can you elaborate? But issues with variability would definitely be a problem. It's not like you could easily make adjustments to such "smart tools", right? So everytime you'd need to swap the tools out for different ones, you'd need to pay quite a lot of money, as you're locked into their ecosystem of tools. But I guess the aviation industry doesn't care about costs as much as your average small business owner. Hell, even the cheapest Russian airlines don't care about any cost under 2000$ when it comes to repairing their planes.

@@diviscadilek1764 Difficulty with things like mold alignment and multi-piece molds, trying to get consistent resin flow through the entire carbon fiber piece, warping and thickness problems. "Difficulty" and "variability" have a lot of overlap, but in general there's a reason people don't use injection molding for parts that are meters long. I could see the cost going up exponentially as the size of the piece increases. For that roughly 1m square demonstration its not too bad, but for a 10 meter wing or flight control surface or even something like a monocoque chassis for a vehicle, these squishy inflatable mold pieces don't seem like they would scale well.

@@HawthornComposites Thanks for responding. From my perspective it looked like it had a lot of the drawbacks of injection molding as far as scalability went, but if you're making 4m production parts its doable at least. I could be wrong but I'm going to guess that it wouldn't be cost competitive with other composite manufacturing for less defense oriented project budgets like medium scale wind turbines? Also: I miss the DoD days when people knew how to name projects. "Longbow Apache" makes sense. "Kratos Valkyrie" sounds like someone isn't even trying to pick names from the same sets of mythology.

Am I the only one, who thinks it is too much manual work for cost savings in mass profuction?! They even use manual keys, not akku or pneumo! Why to put parts in a huge oven when you could directly apply heaters on or In the Alu-forms together with thermal sensors for an accurate temperature control?! Isolate them outside and one could save, I bet, >90% of electicity costs compare to that huge inefficient oven.. And time of course, because to put the thing in the oven, attach vaccum there again. hoses and so on.. again manually... Then detouch. And wait till whole oven will cool down.. each time! Instead of a simple automated press they bolt and unbolt things together.. manually each time. With manual tools. Same for re-shaping of forms.. With the press big enough one could produce one wing at a time, not just 1m part of it. Extremely unoptimised procedure.. year 2021.. Sure, one can use it for private Jets or small series, when price is originally set high. But any startup which will really want to mass produce same staff, will jump forward just by optimised procedure, not even because of another technology..
