In the spring of 2019 I helped the MIT Hyperloop 2 Team with the composite fairing for their vehicle. It is about 6’/2m long and 2’/600mm high. The goal was to build as light a shell as possible that would still stand up to handling and a shiny paint-job. It also had to be cheap, and done fast. This is probably the lowest-tech way to make a relatively light, stiff shell like this. We used all standard materials available readily in most places. The only semi-specialized equipment were vacuum pumps and the use of some pretty basic 3-axis CNC routers. All the wood materials came from local lumber yards.
There is a series of videos on this project, but since pages with pictures too about the design and the tooling which might be more in-depth or specific than the videos. Here are the articles:
