Carbon fiber part fabrication guide

If you’re thinking of working with carbon fiber this guide should be a big help. The example is aimed at the automotive crowd but the principles transfer quite easily. Carbon fiber parts are constructed in a similar manner as fiberglass parts. A mold is covered in a release agent, the fibers are put in place and covered in epoxy. With fiberglass the fibers are often sprayed on but carbon fiber components use woven mats of the material to build up multiple layers. Vacuum bags are used to hold the layers together, removing air and impregnating the fibers with the epoxy. This guide even outlines the construction of a vacuum pump needed for that step.

The benefits of carbon fiber are many, including strength and weight reduction. This makes it a great material for adding parts to weight-sensitive hacks such as quadcopters. But the mesh also has an interesting look which is why it shows up in custom electronics cases. The one real drawback is that when this material fails it is a catastrophic failure, tending to crumble across the entire structure rather than limiting damage to a small area. That means that a rough landing might be the end of your new parts.

Sidecar reminiscent of conjoined twins

Finally, an answer to the problem of sidecar dorkiness. [François Knorreck] spent ten years hand crafting a sidecar with a beautiful design and a luxurious interior for two. The frame is aluminum, the body is mostly carbon fiber, and there are countless details such as automatic chain tension control and steering for the sidecar wheel that make this more than just a pretty paint job.
