+==== 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).
