 +==== Design ====
 +
 +Stefan Laimer and Maximilian Schäferle did a first {{ ::​g4-faserverbund.pdf |concept design}} of a fiber fuselage during the Systems Engineering 2 course in WS20/21. This design is used for the first lamination tests. The design is available in [[https://​cad.onshape.com/​documents/​462341583a3ce9a0ce3df71b/​w/​451ff5ec3fe9085daef8b15f/​e/​eae436c607beb291f9462ec2|"​Onshape - Fuselage Shell"​]].
 +
 +==== Materials ====
 +
 +The [[searchwing-fiber##​membrane_supported_vacuum_infusion_composyst|membrane supported vacuum infusion]] tests are done with the material from Composyst in Landsberg. The other tests with hand lamination and vacuum pressure are done with material from R&G.

 +==== Membrane supported Vacuum Infusion (Composyst) ====
 +
 +A first lamination test with membrane supported vacuum infusion technology was done at Composyst in Landsberg on 19.3.2021. The results are very promising. I have made a [[https://​youtu.be/​bqjWxYAFjBQ|video]] to show the differences between vacuum compression and membrane assisted vacuum infusion technology. (TODO: Describe the process). ​
