I am building a bamboo bike frame and plan to make the joints out of carbon fibre. Some people recommend hemp as a joint because it has a similar thermal expansion coefficient. I however like the aesthetic and structural properties of carbon fibre. That being said, I have never used carbon fibre and am wondering what resin I should use. I am also debating whether to use fabric or tow. I plan to purchase the carbon fibre skinning starting kit to try it out. I will be abutting the bamboo to each other and then wrapping the carbon fibre around the joint. Are there any suggestions or books that anyone can recommend? I am very appreciative of your advice.
Thanks,
BambooBikeBuilder

What I recomend to you is to look on youtube and personal bloggers that do their own carbon frames.... the very most uses aluminium reinforcements on the joint's... the cheap carbon frames on the market are all like that also... I brooke a few....
The best I tink it's to start small scale and try to attach 2 bambo sticks using carbon fiber with diferent twills, diferent resins and see what will work the best....
So u can have and idea what testing is...

Thanks Kyle. I agree that is a good strategy. I work in an engineering department at a university and plan to do structural testing of the bike. I will post videos when I complete them. Any resin/twill combinations that you would suggest?

I suggest that U try to know as much as U can from home bike builders... and companies too... but they are not to keen on delivering information.... the main problem that U will have are the bonding parts.... the stretch on the bambo its not the same that carbon fiber... when stressed it could separate... it hapends alot of aluminium/carbon composites frame.
When U solve that problem, you have another torcion on the back end of the bike.... bamboo seems to me a very elastic material.... the rear triangle of a MTB bike as to be firm... or the power will fade away... for those you'll have to do a very large piece to cover up the bambo and reduce the elastic effect...
I dont have any specific way to do that... I would put together a 90 degree joint with 2 bamboo sticks... and start doing experiments. and forcing then to see how far they go...
Maybe some Kevlar to give some extra support and bonding... try also so sand the bamboo before apliing the epoxy... It's never been done as far has I know... but I know a helmet brand that uses natural fibers from coconuts I think.
So the ideia its not that bad!!!! keep on pushing !!!!

Like the trike, definitely different. I put together a rough old design using good old paint.
