Organic clutches are the OEM standard. As the name suggests their base is of organic origin, usually a phenolic resin or compounded rubber together with cellulose as an organic friction material.
When they're well made organic clutches offer many advantages, which explains why they have been the OEM clutch disk material of choice for many decades. They offer very smooth and gradual engagement which means they are easy to operate and comfortable for daily use and stop and go traffic. They generate adequate friction over a a broad range of temperatures and have a minimal or no break in period.
So let's step things up by borrowing something from bulletproof vests and integrating it into our clutch. Kevlar! When in tensions, Kevlar is 5 times stronger than most steel alloys. This is how it stops bullets. But it can also make your clutch extremely durable and dramatically increase its lifespan. Kevlar clutch discs can withstand higher temps than most organics and will take a lot of hard usage, for example hard driving on the race track, but they absolutely hate stop and go traffic.
Kevlar has good burst strength and great wear resistance if used correctly but it also has a low coefficient of friction, which means it doesn't actually grab very hard. The upside to this is that it usually enables very smooth engagement, just like an organic, the downside is that it needs a very strong pressure plate with lots of clamping force to grab the flywheel without slipping. The final downside of Kevlar discs is that they must be carefully broken in before they can be used hard. Depending on the disc the break in period can be relatively long and ranges from 100 to 500 miles.
A metal clutch disc is also often called a ceramic clutch. Ironically, ceramic clutches actually contain very little ceramic in them, many don't have any ceramic in them at all. Instead the base material is usually copper or bronze or a mixture of both and then iron, steel, silicon, graphite, ceramic or any mix thereof added into in to further increase friction.
Copper and many other metals are excellent heat conductors which means that all metal clutch discs can tolerate extreme heats. It takes some very very extreme abuse to be able to fry a sintered metal clutch, which means you can let loose on the track with them. Unlike Kevlar, metal discs have a very high coefficient of friction, which means they can hold massive power even without a very strong pressure plate, but the downside is that you can forget smooth engagement. High friction means that sintered metal clutch discs grab strongly and abruptly, often with chattering and shuddering sounds and sensations accompanying engagement and disengagement.
But what if even a ceramic clutch isn't enough for you? Let's say you need to transfer something like 1000 hp and god knows how much torque onto your transmission. In that case you need sintered Iron!
The easiest way to understand sintered iron clutch discs is to think of them as ceramic clutches on steroids. They are extremely abrasive which means they will destroy most conventional freewheels. They can hold incredible amounts of power without slipping but their engagement is so sudden they're like a switch. On and off. This means it's next to impossible to use them on the street. On the upside they can take incredible amounts of abuse and it's nearly impossible to fry a sintered iron clutch.
When it comes to twin plate and multi plate clutch kits, they can do something single plate clutches can't and that is to increase the total surface area of the clutch disc. Multi plate clutch kits can do this by using more than one disc. By increasing the surface area multi plate clutches can retain a relatively low clamping force and abrasiveness, which means they can hold more power and torque while retaining OEM like driveability.
Another important distinction is sprung and unsprung clutches and clutches with and without a marcel spring. In general a sprung clutch with a marcel will be tolerable for street driving regardless of material, while a fully rigid clutch will be much better suited for racing only applications.

    When I was working in shops doing clutch jobs, I used to ride with the customer, If they left their foot on the clutch pedal I would void the warranty, some folks would burn up the disc and pressure plate, and ruin the flywheel with in 200 miles, and some fly wheels cant be milled or turned (heat and nasty scoring) holding the clutch down in first gear was a no-no too while waiting for the traffic light to change, or not having the real seal replaced, which should be part of the job, guess you know why I dont work on customer cars any more, the same folks would run brake pads down to the rivets, and turn a brake pad change into a 500 dollar deal.

    Ah, this is a very welcome video! It makes it very clear that the people buying ultra aggressive (race) parts for daily driving are.... not choosing wisely. :) Of note, the company Spec has a lighter than OEM clutch pedal feel (ie. requires less foot force), despite the clamping load being higher. I previous ran a Exedy/Daiken OEM clutch in my 2006 WRX for 6 years - no issues with it, other than being 'vague' with engagement (this is expected in an OEM clutch). My transmission had to be pulled as the Exedy OEM throw out bearing was dying, I opted to have a Spec Stage 1 (organic) clutch installed. The clamping load is considerably higher and the pedal requires less effort. From the rumors that I've heard, Spec re-designs the springs in the pressure plate, and that is the result. I do not have any further details, but that rumor is validated in my experience.

    There are some engines that have 3 pistons and if they don't need one piston, that piston is diconnected. Suposely a L3 should have a dispositon of 240 degrees and a 2L a 360 one to be well balanced. Could you make a video explaining how they do to balance this engine that is a L3 and disconnects one piston?

    Wish I could figure out why the clutch engagement in my B15 Sentra is anything but gradual. I swear it goes from "just starting to bite" to "full grab" if I merely THINK about letting the pedal out. Edit: Whoa... Wonder if the previous owner had a sintered iron clutch installed for some reason. It certainly feels like an on-off switch lol

      @driving 4 answers I never thought of that. For what it's worth, occasionally I will give the clutch a 2-second burn, and it seems to take away some of that harsh, sudden engagement. It is likely placebo, though, and I know I shouldn't do that to it lol

    17:40 it can be bigger than flywheel or pressure plates. Cub cadet did it in 60's. It's an exception so bear with me. Have the organic or Kevlar material be a thick disk with a center hole and 3 oem or 6 aftermarket holes drilled around outer edges that ride on pins so it can slide back and forth on driver. Driver connected to flywheel directly and spins at engine rmp constant. Drive shaft goes in center hole of disk and into pilot bearing on driver. On drive shaft in this order Pressure plate (roll pinned and fixed), organic fiber disk,Pressure plate (roll pin through drive shafy but cuts in pin holes of plate to allow movement) clutch arm,teaser spring( helps for smoother engagement to pre load rear pressure plate),throw out bearing,main spring,and roll pin (oem) or split lock collar (aftermarket tractor sled pulling parts). Drive shaft never moves but the small amount of play in rear pressure plate and the free float of fiber disk is enough to engage and disengage very well. This system could be used in small car applications with modifications but it's not perfect. And there is centered metal multi puck options to replace fiber disk. Works the same check out midwest super cub or vogel manufacturing to see full list of aftermarket cub cadet sled pulling parts. There are multiple kinds but the 1960's cub's have the strongest design and search for (narrow frame models) in the 70's it was changed. Oem from 60's is basically a Marcel with organic and asbestos fiber sandwiched. Or maybe mine was Delaminating it was old and glazed.

    "Transmission" exactly equals 'drive train'. Why don't these people understand this ? It is the drive train that transmits the power from a to b hence it's the 'transmission'. A gear box is a gear box - for the selection of ratios. Some vehicles have more than one gear box - let's give an example of the first gear box giving 5 ratios and the second gearbox giving 2 ratios. It would then be a 10 speed transmission.

    Multi disc clutch is actually easier to slip than one disc clutch. Also it needs less clamping power than one disc. So it's more user friendly than one disc. Only down sides are weight balancing and manufacturing cost, which are exponentially higher and more difficult.

    I think a missed disadvantage so sintered metal clutches is YOU CAN WELD THEM TO YOUR FLYWHEEL. The lighter pressure plates sometimes found can lead to engagement slippage which super heats the surface of the disk, and when it cools, sticks to the flywheel and pressure plate.

    I put a Hyundai Tiburon GT 6-speed manual trans in my 01 mitsubishi Diamante 3.5, it's pretty great! Solid flywheel from the stock (dual mass) Tiburon flywheel, and its a lightweight flywheel wish I would have gone heavier. I experience some clutch chatter taking off from a dead stop. I suspect the springs of the sprung hub are not strong enough for the weight of the heavy Diamante and im getting back and forth movement on engagement, between those springs and rubber drivetrain mounts. This is my strongly felt theory, I will see if my local clutch shop can do ANYTHING about heavier springs, or I may have to try a solid hub clutch disk.

      6-states clutch shop by me does some re-rivoting of new friction material onto old hubs and does some solid hub discs and some with organic material one side and sintered metal on the opposite. I'm considering one of those. My other components were new/machined and I have no problem with runout. Currently organic material disc with sprung hub(for a tiburon).

      Unless the "clutch shop" is manufacturing clutches probably not. What friction material? Were all friction surfaces refinished, or even checked for run out? Pressure plate load?

      why dont you use steering-assist like power transfer

    Very useful. Comprehensive. Well researched. And covers the material science in depth in addition to the dynamics. Much of what is being described here about friction materials also applies to brake pads.

    Hey! You tuned down on the annoying way of speaking :-D . Was I ever the only one complaining about that? :-D

    so if release my clutch, just barely to the point where i have minimal friction and it does a hump noise, it means marcel is done for?

    Very well explained and thank you for including the downsides. When modifying cars I find people tend to mention the pros but not the cons of a product. I didn't know you could get multi-plate clutch conversions, that's new to me. I don't like using the word upgrade for such things as they are also a downgrade in many ways, they're more of an alternative.

      Yes, there are downsides but there are exceptions also. clutch choice is very difficult and good ones can be very expensive. Just because you have a twin plate doesn't necessarily mean it's always less drivable, chatters or is heavy under foot. In my instance (2.4L stroker motor in a evo TME) the stock clutch is very light, so a little extra pedal feel makes it easier to predict clutch take up, still being a sprung centre means it doesn't bang on engagement and the right friction compounds plus double the amount of friction material means it's relatively easy to drive albeit able to cope with more torque (739nm on run in tune, low boost).. My wife can drive it, and in traffic with little fuss. I was lucky, I got my clutch for free, my brother was the sales rep and they used my car as a test bed to make a capable but user friendly clutch.

    Carbon clutches? A panacea? Light, smooth, strong. The only downside is cost as far as I can see.
