PS carbon fibre is stronger than steel so it most definately wouldn’t require aluminium as a strengthening aid
You have to qualify that statement to be fair. It's wrong to mislead readers with generalisations like this. I track a lot of carbon and can tell you (and anyone else that gives a rat's) that it breaks easily - it all depends on its design and layup for the intended use, my CF clipons easily break where an alloy one wouldn't, let alone a steel one.
It's what the OP was posting about, he provided the link, it's in the first post in this thread. I was responding to that, you quoted my response somehow assumming I was referring to your company.
I responded because it is the same product just re-branded as Motocorse so in fact I am responding to the miss information provided by the other vender. I can assure you because the Fullsix Carbon stand is made from 100% solid carbon fibre it is therefor much much stronger than the OEM cast alloy stand. Also you are correct Carbon is only as strong as the shape it’s made in for example a hollow cylinder is far stronger then a hollow steel cylinder of 3 or even 4 times the thickness.
OK thanks for clearing that up. I'm sorry but you're being way too simplistic with your 'facts' re the strength of carbon fibre, you're effectively saying that a hollow cylinder, a clip on handlebar is a hollow cylinder, would only need to 0.5mm wall thickness to match the strength of a steel 2mm thickness tube?
Obviously not to that thickness but if you had a 5mm carbon tube vs a 20mm steel tube of the same diameter then the carbon will be as strong.
The side stand would be more than this, the swingarm, head stock, subframe on the SL would have parts 5mm+ thick in certain areas.
Yes I think parts of the headstock and swingarm would require around that thickness too. Can you rotate the weight of the bike, safely, on that carbon side stand? Does it have a load rating? I watched the video you posted but it was for a propshaft design (primarily longitudinal rotational forces) and they didn't mention the relative wall thickness of either material. What I was trying to point out was that your blanket statements on the strength of carbon fibre vs steel were basically incorrect, you yourself can see that it doesn't work when I gave the clip on example. As a seller of carbon fibre products I'd prefer to see your statements about such things being a bit more precise otherwise it starts to come across as some kind of Wild West snake oil sales patter IMO. FWIW if you were not a CF products seller I'd have still called out on it, it's not a personal attack.
Fair point. The point I’m making is the same as for instance a Spider web, relitively it is stronger than steel, same with carbon. The video you watched you can see how much more strength the carbon can endurer being the same thickness as the steel counterpart.
Yes you can rotate the bike on the stand, I had one fitted to our show bike and did it plenty of times however I wouldnt advise doing it due to the plate that is attached the the bottom as this could be twisted away from the carbon. With regards to your clip-on bars I cannot say as we have no idea how they were manufacturered but you can see from the video Carbon is stronger otherwise it wouldn’t be used on such vehicals like F1/MotoGP/Yachts/airbus etc etc
I'm sorry but you seem to be digging an even deeper hole for yourself here and seemingly demonstrating that you have little engineering knowledge at best. I have already tried to draw your attention to the fact that the video you posted does not even discuss material thickness yet you have continued to use it as 'evidence' to back up your false statements. That video is for children ultimately and does nothing to back up any of the erroneous points you've made, yet you seem willing to pull yet more non-facts out of the hat to help make your argument. That you are happy to try and convince us of these 'facts' does not come across well IMO. You don't seem to want to acknowledge that.
Your link completely contradicts itself..... Spider silk, then, is stronger than steel on a per weight basis while being very environmentally friendly. This may not have the same pithy ring to it as "spider silk is stronger than steel", but it tells a much more dramatic story about why the mimicry of natural materials is a rapidly growing area of materials science and engineering. Exactly the point I’m making!! http://www.planet-science.com/categories/over-11s/natural-world/2012/02/strong-like-spider-silk.aspx
