+==== 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"]].

-There must still be air/voids in the laminate although it seems optically in good condition. The fuselage half has weight of 116g.

   * Hand lamination without vacuum. The hand lamination will have more resin in the laminate and the surface seems closed. No idea if the voids are reduced or if there is just a closed surface.
   * Vacuum infusion. Compared to vacuum bagging literature claims that voids are reduced with this technique. The VAP membrane technology might be a way. This promises a void free laminate with a high fiber content.
+  * Degassing the resin. Is probably useless for hand lamination because bubbles are introduced during the lamination process.
