With this qualification you should be able to address my biggest question here: if he is correct in saying that graphene doping bonds the resin to the fibers and also increase the strength of the resin, shouldn't we see a DECREASE in toughness? The toughness of composites lies in the separation of fibers and resin upon impact which avoids stress concentrations and stops cracks from developing. If we make it a "uniform" piece of material we are actually interfering with this beneficial effect. What in my opinion it does is simply increasing the amount of fibers we can add without incurring in viscosity issues, still retaining the beneficial strength sheer between resin and fibers. Would love to hear your opinion on this one.

As someone that is doing a Master degree in materials engineering, this video was absolutely a load of... accurate information. I'm glad that GCN made this video to help the average cyclist realize that graphene is not replacing the carbon fiber themselves in a carbon fiber composite, but rather just an additive to the resin system. However I am a little doubtful about achieving a conductive frame from using graphene because that will require chunks of graphene (lets face it, it will be impossible to obtain individual separate graphene mono-layers when mixed within the resin) to physically be in contact with one another. That's both incredibly difficult to achieve when dispersed, unless a incredibly high volume percent of graphene is used, and can act as defects in the finished products because load transfer is reduced. All in all it will be interesting to see whether this idea succeeds or not. I know that Cervelo tried putting silica nano-particles in their RCA frames for the same reason, but I think they have since stopped. All in all thanks Si for this video!

You lazy materials scientists, what have you invented for us this week? 😉 I have to say you'd have to lay graphene circuit trace layers into the frame, extra complication and not needed as quite a bit of that technology for shifters and dropper posts can now run wirelessly. The biggest weight saving would be going back to basics and incorporating the same weight savings into the mechanical parts and cabling, hubs and wheels. Though at what point have you gone too far? When you are to scared to get off your bike in case it blows away? 🌬️🚲

The point of light equipment is not to give average people massive improvements but to not leave any stone unturned when looking for more speed. These are useful when losing 10 more pounds would make you slower (there is not fat to lose, virtually only muscle is left) or be detrimental to your health (some people need more fat than others or they will suffer various complications). The reason people buy these bikes is because the marketing operation is on point. This is one of the most expensive sports and gullible beginners believe they need to use the same equipment that the pros use. If it were possible, most people would rather pay extortionate amounts of money to get the gains than to put in the long, hard work. In fact, this is what they think they are getting when buying these artificially overpriced bikes and other equipment.

Interesting explanation. "Graphene" has been a bit of a buzzword in material sciences for a while, and mostly presented as an 'alternative' or 'succesor' to carbon fibre, but that doesn't seem to be the case as it's not replacing the material altogether. Rather than talking about "graphene bikes" - whose benefits are phrased in terms of the properties of pure graphene - perhaps we should be talking about "graphene fortified carbon fibre bikes" (although that's admittedly a bit of a mouthful). The funny thing is, it's not even the existing fibre where the gains are being made; it's the resin, which up until now has been the element of carbon composites that have had virtually no sex appeal. To the extent that people omit its existence altogether when they talk (technically inaccurately) about frames being made of pure carbon fibre. So yeah, carbon fibre isn't being replaced or phased out. It's just being beefed up with resin-on-steroids (possibly to great effect).

Yeah, that sounds sensible. I was mainly talking from my own experience of being confused between "pure graphene" and "graphene as applied in the real world". Before watching this I was under the impression that graphene was going to take the place or carbon fibre in road bike design (doing the same job, but lighter), but this video has really clearly explained how it's going to be worked into the process. I wonder what terminology will spring up if an when these kind of bikes become mass-market. I like the term "carbographene", personally.

roland H As a chemist I can say that you basically put tape ( yes sticky tape) on a a highly organized graphit body and pull of a couple of layers of graphene form it. The Oxygenplasma is used to build small plateaus on the surface of the graphite, so that you pull of as few layers of as possible. As for now you need a lot of time, to produce small high quality amounts, but as research advances, new more efficient and or greener methods are found. And you do not need so much graphene for a bike. Aluminium on the other hand is not environment friendly at all. The extraction and purification processes for Aluminium use up a lot of energy and highly corrosive chemicals and produce highly toxic byproducs. But of course you can recycle it to reduce the ecological load.
