A carbon fiber bike filament winder controlled by Arduino

Arduino TeamJanuary 18th, 2019

Bryan Kevan wanted to build his own bicycle, but wasn’t satisfied with purchasing a frame—or even ready-made tubing. He instead chose to create the frame from raw strands of carbon fiber

The overall bike build is shown here, which necessitated him designing a variety of jigs, including a CNC wrapping machine.

His device uses an Arduino Uno, along with a pair of driver boards, to carefully roll strands of carbon fiber on a PVC mandrel in an overlapping pattern. Epoxy was dripped on the assembly during the process, resulting in CF rods that were lighter and much cheaper than purchased rods. 

After quite a bit more work assembling everything together, Kevan now has a bike frame that is truly made to his specs!
