    Carbon fiber bodies?

    Has anyone made a carbon fiber body? It seems like the PERFECT thing to make out of carbon fiber. I was considering doing it a little while ago but never did. I might do it now since I have to build a hatch for my boat so I'll already have carbon fiber and vacuum bagging supplies.

    There is one for the Baja. But its not very practical. Carbon fiber almost always breaks when hit hard and the price vs. lexan is very high. And while this may sound strange there is also a weight issue. Carbon fiber is much heavier than lexan.

    I was wondering about the weight...carbon fiber is lighter and stronger than say, solid plastics and certain metals typically are, but bodies are more flimsy plastic...the flex helps absorb and dissipate any impact damage. The More rigid the body the harder the impact parts that are not used to it, which can make things break.
    Now, by all means, do not let me or anyone else to stunt your creativity. These are known flaws. Any time a designer takes flaws into consideration, when attempting a new design, they may stumble across something unique.
    I'm crazy, no really I am.

    Yeah... I thought about all of that. I still think it would be pretty sick. CF is actually INCREDIBLY strong if you use it right. With proper reinforcements and resin content, I'm sure that it could hold up at least as well as a lexan body. It would weight slightly more though. I guess no one has done it? I'd love to be the first

    There was a guy selling C/F bodies on ebay for a while. I just did a quick search there and came up empty so it kind of looks like he gave it up.

    It really depends on application. I can see having a scaler body made of CF. I can't see using CF for a go-fast RC, it would be a lot heavier than a lexan body(CG would be a lot higher), and, as meantioned above, it would like get cracked or broken.

    In some ways carbon fiber is incredibly strong. But it does not respond well to being hit. Just like hardened metal its strength comes at a price. You can try to make one but its a one shot deal. The first good crash is very likely to crack or damage it. But a lexan body can take tons of impact abuse. Because of this it became the industry standard.

    I think it became the industry standard because it's cheaper and MUCH easier to produce... especially in large volumes. It's the same reason they don't sell a Rustler with an aluminum trans from the factory, include a lipo instead of a nimh, or sell all trucks with big bores. They are all optional upgrades, should the owner want to buy it. The same goes for a CF body. The thing about a CF body is that they are simply unavailable, even if someone did want to buy it. Maybe I'm wrong about the strength of a CF body. Maybe it really would shatter on impact. There's only one way to find out.

    Lets go for a large leap here and say that not only is it stronger and more rigid than the stock body but lighter...ok, so what? your forgetting a very important law in physics...All energy is transferred, energy is never created or produced. Lets say that body survives a high speed impact. where will all of that energy go? Its likely to brake the next weaker component, if not multiple components.

    Back in the day RC's came with hard plastic body's. People soon found out that a few crashes would destroy them and now they are only on slow or collectible RC's. Carbon fiber has even less give and once broken may as well be thrown out because a second crash will be even worse. Carbon fiber is strong only in applications where it does not have to move/handle impacts. It is not just all around strong. You can try making one but you have been warned about what will happen.

    This was Standard on Traxxas kits before the Rustler >_<

    Yeah... I see what you're saying... but I'm not talking about a basher body here. I'm talking about a body that would go on an XO-1 or something. I think it could stand up to a pretty good impact if built properly.

    You may have missed the point. I was getting at the fact that Traxxas doesn't build their cars and trucks with the best stuff out there. They do their best while keeping it cost effective.

    not always true. Plastics have come a long way since traxxas was first founded. Now in a lot of cases plastic can have a longer durability due to heat build up, dissipation, friction, and higher flexibility.

    Then explain to me the entire RC aftermarket industry? Why is it that when someone builds the ultimate (insert Traxxas vehicle here), there is just about nothing Traxxas left on it? As I said before, they do their best while keeping it cost effective. It doesn't make economical sense for Traxxas to make a vehicle using the very best technology and perfect materials.... nor does it make sense for, say, RPM to make an entire RC.

    I'm sorry but I have to disagree with you on that one. Competitors are selling more modern base trucks with aluminium shocks, metal motor plates and even a seal gear diff or ball diff as standard equipment for equal if not less then a Traxxas product. Traxxas does make a aluminium shock that has a smaller diameter then the big bores which should be STANDARD and and have the Big bores as the upgrade. Traxxas also had a transmission that can use the same internels has the VXL and come with a metal motor plate and gaurd which was around since idk 1990 which is a couple years before the Rustler. Aluminium shock and a metal motor plate should be standard equipment. I can see selling the XL-5 series in the current form but drop the price to make it more attractive compare to the competitors entry level RTRs and have the VXL series come with the upgraded shocks(even big bores) and a metal motor plate design.

    its interesting you picked RPM... hardened plastics...lol

    besides, keep in mind, just because its the strongest for its piece, does not mean its good for the vehicle. some large vehicles have natural soft spots, so that the energy absorbed does not go into more vital spots like say the cabin. that easily could be applied to RC cars.

    I don't see what's so interesting about it. It's a softer plastic, more suited to the abuse seen a basher style RC and can be used as a strategic soft spot in suspension components. Also, are you saying the body of an RC was designed to act as a crumple zone?

    yes, the body of an RC absorbs impact so the rest of the car does not suffer such heavy impact damage.

    it is interesting because I made a comment about plastics being superior to metals in some cases. Then you asked me to explain the aftermarket industry, while refering to RPM. once again, RPM is nothing but plastics...so therefore, why do I need to explain an industry when you did that for me.

    Also You understand the need for better plastics, which still have flex, but your trying to compare plastic to carbon fiber. Which I believe the point has been made more than enough does not have flex. 2 different materials, 2 different uses.

    Haha ok. I'm done arguing. We are just going to have to agree to disagree. We could go back and forth for days. If I get a chance, I'll make a carbon fiber body. Maybe I'll prove you wrong... or maybe I will realize you're right. Either way, my original question, "has anyone made a carbon fiber body", has been answered. It's been done by some guy on eBay but no one seems to know what the results were.

    sounds good, you should update us with pics of the body after you make one. I would love to see them, as I am sure many others also appreciate someone else's hard work.

    Will do. I'm still not sure if it will actually happen. It all depends on whether I decide to go with CF or fiberglass on a hatch for my boat and if I decide to vacuum bag or not. It's not worth it, IMO, to buy CF and all of the vacuum bagging materials for a body that may or may not work. If nothing else, it can be like the Integy piggyback shocks... they look awesome but just dont work for anything but a shelf queen.

    I have been looking at my Jato, considering making a formula body for it, if I cant find one, but I have no idea where to even start lol.

    Once set up with the vacuum bagging stuff, an untrimmed body is a perfect mold so I could make just about any body out of CF relatively easily.

    that brings up an advantage you could possibly have for your vehicle, using cf. If you can create proper down force with the aerodynamics it could help with control of the vehicle.

    I suppose I could make a plug out of a body and modify it. Now you've got me thinking.

    I was thinking... I know they make a carbon kevlar hybrid. I did a quick search and found it. This may be the solution. It combines the lightweight properties of carbon with the impact and abrasion resistance of kevlar. It also looks darn good.

    Like I said, Knowledge of known flaws, tends to leads to unique discoveries. Definitely worth even further looking into. seems your onto multiple things now.

    Yeah. I think I'll do a little R&D and take this concept into reality. Who knows... maybe it will be the next big thing!

    Strongest stuff I know of is carbotanium. But even that wouldn't work well. It might hold together but its gonna look like a busted up windshield after a few hits.

    Wasn't there a thread on this forum a few years ago with a guy making CF bodies for the Rustler or one of the trucks?

    I know there were links posted on the forum to them on ebay. I seem to remember one for the mini Revo and some other model. As I recall the guy used ProLine bodies as his mold not Traxxas bodies so there was a Slipstream and I think a Desert Rat for the Rustler.

    I do remember seeing some ones on here before and i was going to make one last year but i never got the money to do it and forgot about it. the thing is you probably wouldn't be able to sell them im you base it off of the traxxas or proline body i think, but i could be wrong.
