rudi-h Posted July 27, 2011 Share I've been playing around with the idea of making something from carbon fibre, and maybe one day when i'm big i'd like to build my own frame. Anybody have any experience of how to do it, where to buy the carbon and resin etc? Link to comment Share on other sites More sharing options...
EigerSA Posted July 27, 2011 Share where abouts are you? you can get from a place in Umbilo road (Durban). It's not too expensive, but you limited to the weight of cloth available in South Africa. Actually using the stuff is pretty simple, easier than fiberglass. what's important to know is that layers of carbon fibre don't "stick" together, which is why most manufacturers use vacuum systems, also the orientation of the fibre's make a big difference strength wise.. Loads of youtube videos, mostly for car parts but still the same. otherwise check out bruno's site here for how he built his carbon fibre bike http://www.bmeres.com/images/carbonbike.jpg and instructables. good luck.

rudi-h Posted July 27, 2011 Share Thanks! I'm in Joburg, so i'll look around on the internet a little more Link to comment Share on other sites More sharing options...
The OriginalSpartacus Posted July 27, 2011 Share "Before wrapping, I perforated the tape with a pin over the whole surface. This squeezed out excess resin after wrapping." that must've taken him forever!! Link to comment Share on other sites More sharing options...

Bobbo_SA Posted July 27, 2011 Share AMT near ORT has all the cloth and resins you will ever need, :-) http://www.amtcomposites.co.za/ Link to comment Share on other sites More sharing options...

EigerSA Posted July 27, 2011 Share i think he left it in there, added little in terms of weight but did improve stiffness i think Link to comment Share on other sites More sharing options...

Sounds like it stayed in there anyone know if someone has turned normal road rims into Carbon Deep Sections? How would one bond the Carbon to the Alloy rim?

Minion Posted July 27, 2011 Share anyone know if someone has turned normal road rims into Carbon Deep Sections? How would one bond the Carbon to the Alloy rim?Since it's non-structural, the epoxy resin would provide enough bond to keep it in place. Link to comment Share on other sites More sharing options...
brad890 Posted July 27, 2011 Share Where would one find, things like the drop outs and bb shell etc if you decided to build up a frame Link to comment Share on other sites More sharing options...
Brian Fantana Posted July 27, 2011 Share the only thing i'm curious about is how did he remove the polystyrene from the inside of the finished frame, or was it just left there? The polystyrene can be removed by pouring acetone into the frame, which will dissolve the polystyrene. A jelly type substance will then pour slowly out of the frame. One just need to make sure that the resin or epoxy used is acetone resistent. Link to comment Share on other sites More sharing options...
Grebel Posted July 27, 2011 Share Where would one find, things like the drop outs and bb shell etc if you decided to build up a frame I am sure there are a few broken frame lying around your LBS that they would be happy to part with for a few rand.

EigerSA Posted July 27, 2011 Share just keep in mind that you can't bond metal direct to carbon fiber, you need a buffer of fiberglass or else you get corrosion at the joint. @brad890 parts can be ordered from columbus tubing or henry james.

I'd love to build my own carbon frame but doubt it will happen any time soon. Am just finding this thread interesting. and who knows maybe one day i might just build my own lol Link to comment Share on other sites More sharing options...
