- In this video you see how to make a really simpl flexible heater out from Carbon Fiber.
For this project you need graphitic carbon fiber, for the heating element and copper or aluminium contacts.
Link to Graphitic carbon fiber: www.ebay.com/itm/3-5-8-10-14m...
With 10 volts and 5 amps I get 170 degrees C.

Thanks. good instruction.
How big is that carbon fiber 3mm mat
Hello. A very successful design.Is this heater moisture-proof or not? I want to use such a heater to heat the seedlings. Is it scary if water gets on the fiber?Thanks.
A better way to put those two ends on would be to put it in a Vice and really clamp it down! Much easier than bashing it with a hammer.
From where i can purchase the first carbon fiber pad. Thanks in advance for sharing the link with me.
Search for pan based graphitic carbon felt on ebay.
What will happen if i connect it to + and - home socket (AC Supply)? Will it work for 5V / 2Amp ? If i leave it on heating continuously then can it burn at some point of time ?
Please help me understand , thank you
Does it heat both side or one side? All carbon heaters heat with both side? Sorry for my English I hope you understand. Thanks for your answer.
The heat will be on both sides. If you want to heat only one side you need to isolate one side with some glass fibers
We need to connect the power supply to the flexible heater all the time to get the stable heat, right ?
Yes. You need power supply or batteries for stable temperature.
It’s a very interesting heater… sadly your link to eBay doesn’t work. Can you describe exactly what kind of carbon fibre it is, or give a working link so that I can find it in Europe please? Hope you find the time. Love your work!!
Search for PAN based graphitic carbon felt and you will find alot of that stuf on ebay or I think that you will also find here in Europe. I buy that felt on ebay from china
@@cayrex I had exactly the same question. Thank you 👍👍
Thank you so much. Want to make one to cook on!!!
No problem 😉 for cooking you will need more power that you will get the temperature of 250 to 300 degrees C. For that you need 100W (10A and 10 volts)
cayrex2 Thank you!!!
Fransje Bik no problem 😉
You can cook on the first one but the latter might be useable for clothing
Right. But also the first one can be used in clothing,.... you just lower the voltage.
Hello, if I like to use this as a heating pad for clothes, what temparature can I get out of this, if i use for sample 12 Volts with 3 amps for maximum ? And what possibillitys I have to put a flexible power connection on it, not using the aluminium plates. Please can you give me some advice ? Thank you !!!
Hello! So, you maximum power will be 36W I think that the temperature will be around 80 degg C, but I am not 100% sure. You need to test it. You want to replace aluminium electredes with some flexible material,.... hmm, this is a little tricky. You can use a aluminium or copper foil, but in this case will be hard to conect the foil to carbon fiber.
Where can I buy the carbon fiber
can I use 12v -10amps power supply with the second type of fiber I have 36 x 91cm you use in the video
Yes you can try
Hi! I'm working on a University project and I'd like to know if I can use this Carbon Fiber Heater in a Toaster. Can you give me some guide lines? Like, what will be the limits, do you think it could be risky? I think that the toaster should reach 180°C, is that okay?
heh interesting. Carbon fibers heating element into a Toaster. Yes sure you can try. Safety: the carbon fiber cover into some tape like kapton tape that you will not have the problems with fibers that coming off. Make a 12 or 24V version,.... because carbon fiber is good conductive,... you can make a 12 or 24V toaster. Uff, I dont know what is the temperature of a toaster. More heat,... faster will be baked bread 🤔
Hello, very interesting .do you have a special regulable power supply? I tried with a regulable 30V 5A Power supply , but it don´t works. The P Supply don´t allows to set for example 10V with 5A. It changes automaticately the scale to very mínimum values ( 2v 1A) , best regards.
Hi! no, I dont use any special power supply. hmm, interesting for your results. try to set your power supply to full power and you will see what output you will get.
Hello @@cayrex Thanks for your answer.I´ve seen your video about conductive Ink infrared heater.What type of power supply do you usefor this? best regards have a nice week end.
@@FJPW07 I always use the same power supply.

I can imagine one cut to be a warmer for dinner plate.
Hehe yea
How hot can this get before it damages the power supply or blows a fuse?
400 - 500 C
What precautions should be taken before working with carbon fiber?
Full protecting breading equipment.

Sir i want this material i.e 1st one which thick
So where i can get it on ebay it was absent
I dont know how thick material you need. But you need to know that more thick is the felt more conductive will be. I use felts in thicknes of 3mm,.... for some projects I also use 5mm. On ebay search for PAN based graphitic carbon felt and you will get some hits.
Lets work on a iron nickel printed battery design. Silk screen the ink. I’m finding sizing material holds up in chemicals.
Why silk screen the ink? To produce a smaller particle size?
zacariah heim doesn’t have to be silk screened. I’m just wanting a simple process to apply it even. I’d rather do it with a additive printer. But silk screening is a simple process
For a Ni-Fe battery the best option is to opt for freeze drying the ink into place once applied to the electrode. This creates a free standing electrode/active material mixture. Graphitized Carbon fiber weave being the electrode material. This will increase ion flow speed and charging speed, as well as capacitance, while lowering the internal resistance and providing a much lighter weight battery design. Polyethylene can be used as the separator material, with a Gel electrolyte. The key, is finding a way to maximize the chemistry by finding a way to prevent parasitic hydrogen generation. One one is to add metal sulphates, but you can also do this by making the Iron electrode carbon from Garlic biomass. Extract the biomass with ethanol to make a concentrated garlic oil, use this as the binder for the ink. The natural sulphur content will help to prevent hydrogen generation, while adding Lithium hydroxide will increase charge density. Many many changes to a Ni-Fe battery are possible.
zacariah heim ionic solution doesn’t gas. Also it needs to be thin layers to print on paper. One side paper be the proprolene
I would suggest to use copper instead of aluminum
Yes. At that time I only had aluminum on hand
Can this be heated using an USB powerbank?
In basic yes, you can use a battery power bank. But the heat will be a litle lower.
I would suggest getting a little better understanding of what is at play here before experimenting, I'm truly trying to help so I hope this doesn't come off wrong. But maybe do some research on Google first to help understand how this works a cliff notes version is the carbon fiber is acting as a resistor (resisting the flow of electricity aka energy) when the electrical energy hits this resistance it starts to shed off some of that energy into heat( basically a different state of energy) so the more resistance the more energy that is turned into heat(* a bit more nuanced man that) but also the more energy that you put in to a resistor the more of that energy gets turned into heat. Kida think of this as a reverse solar panel. (Kinda) it's just converting energy from electrical energy to hear energy. Energy is sometimes refered to as potential too. Google "resistance heating" or idk... Stuff like that. Also keep in mind the longer the strip of carbon (or whatever you use for a resistor) the more resistance. I hope I didn't mess the idea behind this up too much. Please let me (,and this guy) know if I slaughtered that too badly. One last note is a usb power supplies well generally have a 1.5-2.1 amp 5 volt direct current. You will need to know that for figuring out your math/measurements
@@danskustomairbrushin hehe, now you explained basic of heating, which is cool. So almost 99% energy is converted into heating/ir energy in this or other commercial available carbon fiber heaters. The surface of the heater is heating up because of the resistance of the material, but also the heater create a far infrared waves. More energy you put into the heater higher will be the surface temperature because more energy is converted into the heat, but the amount of the far infrared waves will be almost the same,... because the surface area of the heater is the same,.... to increase the amount of the infrared waves you also need to increase the surface area. The power bank have the output power of 10W, in this case you also get some temperature, but will be enough for some poket heater.
link of carbon fiber is broken.. Which type of carbon fiber is it, to be able to find and buy it? Thanks!
Yes, this happens many times. Search on ebay for PAN based graphitic carbon felt
Thanks! Is it more suitable for making DIY heated gloves than a 3k carbon fiber fabric? Rigidness, temperature, energy required, workability...
I think that carbon felt is a bit better to work with as 3k carbon fiber. but it depends on each individual what is better. For heated gloves I make a small heater with conductive ink and kapton tape for example. In that case I can conntrole the resistance of the heater. And the heater I can simply stick in the top side of the glove.
@@cayrex what do you mean by controlling the resistance?
With the coat thickness. Carbon felt or fibers have the set resistance and you can not change the resistance of felts,... the resistance is what it is. But with conductive ink I can make less or more conductive with applying less or more layers. For example with 1 layer I get 20 ohms,.... with two layers or a bit thick layer I will get around 8 ohms,... etc
can i plug it in with ac 220v?
Direct to 220V? You will blow up the fuse.
Let's do some math this material is commonly 8 ohms per meter, at 220 volts we would need 22 ohms of resistance to pull 10 amps of power 22/8=2.75 so you would need over 3 meters to connect this directly to 220v. If you connected that tiny piece he has it would pull over 30 amps and instantly trip your breaker
Oke thanks sir, does it have to be with aluminum?
@@canriz8345 what, the electrodes? No, can be also a copper.
I tried, by clamping the zinc, but the carbon fiber not heat
Your link didn't work
Yes, because the link is ultra old. Just search for Pan based graphitic carbon fibers
So the felt is at 81C and your hand your hand on it for at least 20 sec, that is indead working smart
😉👍
carbon fiber probably has health risk, maybe not good to be used as a heater
Do you have any source for this information? I would be interested if so. I do have a hard time believing this to be honest.
Sharp small pieces from the second swatch of material in this video could be hazardous if inhaled. The soft pan carbon felt shown at the beginning is pretty benign, although I would not advise it as a filter for a face mask, it might work well as a seat cushion fart filter.
