Is it possible to electroplate carbon fiber? Answered

Hi, I'm into knifemaking. There are some carbon fiber knives on the market, but they all have very poor edge retention. (because the edge is made of carbon fiber as well) I was wondering if it would be possible to add a thick metal coating of a hard metal to a carbon structural center, as to coat the blade in a thin layer of metal. This metal would then be serving as the cutting edge, hopefully with better edge retention.  Is this at all possible? What types of metal could be used? Thanks in advance!

Wrapping wood in carbon fibre.

Hi, After cutting my own wooden lacrosse shaft using the tutorial on Instructables, it snapped within half an hour of use. Now I know this was because the grain was pretty poor and it was not a strong wood, but someone suggested that I wrap a shaft in carbon fiber so that it is slightly stronger, limits horizontal movement and reduces denting. I just have a few questions about trying this; Would this carbon fiber be appropriate for the project. http://compositeenvisions.com/raw-fabric-cloth-2/carbon-fiber-97/carbon-fiber-fabric-plain-weave-3k-5-7oz-tape-605.html if not where should I look? The biggest problem I see is somehow packing the carbon tight around the shaft so there are no bubbles and it is consistently straight all the way down the shaft, there is a vacuum packing basics tutorial on instructables but I'm not sure if you could use that for a lacrosse shaft. Instead of making my own bag as per tutorial would just a plain bag (http://compositeenvisions.com/vacuum-infusion-equipment-71/nylon-vacuum-bagging-film-500.html) be fine then clamp off the unneeded extra, although are those bags re usable? Because I don't want to have to pay $5 USD every time I would like to wrap something. I saw something called bleeder cloth as well, would this be needed to stop excess resin sticking to the shaft? When it comes to the carbon, I know someone who sails a lot and has some experience with carbon fiber but none with vacuum packing who said I should lay it up like the image attached to decrease horizontal movement while allowing vertical flex. Would this have the desired affect as if this is successful I plan to make a ton more for a high school team I help coach. I've attached a image to give you some idea of what I'm talking about. Then for the actual laying of the carbon itself, a shaft is not a flat surface so you can't just pour it on like the Youtube video's I've found. I'm not sure how to pull this off. Then afterwards, is there a simple way to test the properties of the shaft; specifically flex and impact strength. Because even if I don't end up wrapping the shafts I still need to test the wood to compare it to alloy. Sorry about the small essay, but I would really like to give this a good shot. Because shipping shafts from the states is quite expensive, being able to make my own and then put graphics on them would be amazing.

Witnessing Human Flight

First posted here. Last Friday, I drove up to Maryland to see UMD's Gamera II human-powered quadrotor. They are currently pursuing the Sikorsky Prize, established in 1980. Here's the team testing a new control system. http://youtu.be/3B2of4V35d0 (sorry, the embed function isn't working)   During this test, Gamera II flew for approximately 65 seconds, unofficially tying the endurance record that the team previously set. This flight time, plus the ability to remain within a specific boundary, satisfies two requirements of the Sikorsky Prize. Because the rotors are so close to the ground, the helicopter is benefiting from a cushioning effect of the air between the rotor blades and the ground. This effect will diminish exponentially when the team attempts sustained flight at the required 3 meters. The helicopter transfers the pilot's pedal power by unspooling cable from pulleys, mounted on the shafts of each of the four rotors. Flight time is limited by the pilot's stamina and the amount of cable stored in each pulley. The rotors are constructed of carbon fiber, balsa, and foam, and are covered in a plastic film.  All in all, it was a cool experience. I've never seen so much carbon fiber in my life! I look forward to seeing the team win the Prize.

What profile of pole would be torsionally rigid? Answered

Calling all mechanical engineers and physicists. I want to make a pole that can resist twisting forces. The application is a down tube on a bicycle frame. And I want to use bamboo because it's light, very strong, very cheap, and biodegradable. The problem with bamboo is it lacks torsional rigidity because its fibers only run lengthwise. I was thinking of wrapping a bamboo pole with a composite fiber (hemp and glue) at a 45 degree angle like they do with carbon fiber poles but maybe a different shape would be better. Can anyone think of a specific geometry of pole that is tortionally stiff? I noticed some bicycles have a triangular down tube. Maybe if I cut bamboo into three strips and glued them together into a tube with a triangular cross section, this might be less twisty. Am I thinking along the right lines here? My first bamboo bike has a lot of twist and this might be one way to make it stronger. Please let me know what you think. UPDATE: The issue was many fold. The short answer is Tonkin Bamboo is the species to use for bikes. This is what most people seem to use. Also Boo Bikes use dendrocalamus strictus (aka Iron Bamboo). My frame had some cracks possibly due to harvesting at the wrong season. I've recently gained more cracks and the bike flexes even more. It flexes like a noodle but I can still do an endo no problem. Go figure. Also hemp sounds like it gets more stretchy after being flexed about 1000 times whereas carbon fiber stays stiff. And squishy wood glue is probably not as stiff as epoxy. All this adds up to a flexy frame. My next one will be tonkin bamboo but I will try hemp and non-toxic wood glue again. UPDATE #2: I'm making a three wheeler and my engineering design teacher gave me some advice involving spaceframes and triangles. The plan thus far looks like this upright tadpole trike: UPDATE #3: I think I've got it! Instructables sent me a box of K'nex and I built up a model of a standard bike's frame. The thing is, when a bike frame twists, the opposing corners of the trapezoidal shape come closer or further apart. So a deep X brace from corner to corner seems to fix most of the problem. I'll try to post a youtube vid of what I mean soon.

Tiny Wind Turbines that Could Power a Home

Everybody wants to have a cleaner Earth, but few of them take any actions. One of those people is Doug Selsam, who designed high-power wind turbines that can generate enough energy to power a home. The wind turbines measure about 14-18 inches in diameter and they can generate an impressive amount of 200 watts for a 20 mph wind, but the wind turbines could do better if the winds are stronger.Selsam's wind turbines are made of high-strength carbon fiber materials which give the turbines the possibility to be hooked as one. This system is very simple and it weighs a bit, as you see, it can be held in one hand.

How can I make cheap honeycomb core boat hulls

I saw a 'How It's Made' episode where they revealed how to make honeycomb core simply by making a paper accordion, expanding it, dipping it in resin then sawing it into cores. I WANT TO DO THAT! They said they used a thermoplastic paper as well as a heat-activated glue. But why couldn't I use a cheaper more readily available material? Does the resin provide ALL the structural strength, or does the thermoplastic paper itself provide the strength? I would assume it's like fiberglass, whereby after it's infused with resin it's super tough... but the fiberglass itself provides strength too... What kind of material could I use for this? Straight up craft paper & elmer's glue? After the cores are cured and cut, I'll sandwich them between various layers of either wood laminate, plastics, fiberglass, or carbon fiber. Thanks!

Something like this: http://www.featurepics.com/FI/Thumb300/20100216/Black-Metal-Grid-1460869.jpg And really basic animations for the eyes, like fading in & out, flashing, standing still, etc. The base could be made from fiberglass or mabye carbon fiber. The eye "lens" maybe could be made from plexiglas or something like that. And the "headphones" could be the part of the helmet, with built-in headphones. I just slighty edited the design of the original PSN robot helmet, which looks like something like this: http://www.4shared.com/photo/3miIkBII/robothelmetdesign.html PLEASE! I just want to know who could do one for me or at least how could I start to make the helmet! PLEASE HELP! (And sorry for my English...)

RC helicopter Hirobo XRB with pics now!!!!

I have a Wireless remote control twin blade helicopter for sale. This is not the cheapo mini copter you see on Ebay. This is an hirobo XRB, cost me $400 new still have the reciept. Comes with xtra rotor blades, remote, Lipo batterie. I have cut some of the plastic away to make it lighter in weight. The X and Y axis are adjustable on the heli and the radio. It flew great 1 year ago, The blades are a foam composite, ( you can buy carbon fiber ones online.) The colars where the blades mount are broken, so if you want to use it as the heli you have to purchase new ones from Hirobo, couple bucks I assume. Twin roto design ( no tail rotor ) this allows you to take everthing off including tail boom and jus tfly the little silver box in the center if you wanted to. Or you can use it for whatever you want to, everyone in this community is quite creative, I however am not. Someone can build some cool stuff with this. $100 OBO
