Step 13: The Rest of the Joints
One disadvantage of the hand layup / compression wrap method is that it tends to be fairly labour intensive. It is more difficult to achieve a uniform wall thickness of carbon on your part, and there will almost always be a fair bit of sanding required to get a good finish. Sanding carbon fiber is a pain, and also breaks the long strand fibers that make the part strong.
I wanted to take full advantage of 3D printing technology for this project, and decided that I would create 2-part female moulds to complement the male “core” sockets that were used to jig the frame together in the first step. I could then lay my carbon fiber into the moulds and clamp them over the joint in order to get a compacted, uniform joint which would require less difficult post-mould finishing.
