===== Fiber Wing =====

Description of the fiber wing design, analysis and construction.

==== Materials ====

  * Core Material: [[https://www.styrodur.de/portal/load/fid1360376/Styrodur_Technische_Daten_DE_Mai%202022.pdf|BASF Styrodur 5000 CS XPS (50 kg/m3)]]
  * [[https://www.r-g.de/en/art/100130|Epoxy Resin L + Hardener EPH 181]] 90 Minuten
  * R&G Glasgewebe 49g/m2, Leinwandbindung ([[https://www.r-g.de/art/190105|190105]])
  * R&G Glasgewebe 80g/m2, Köperbindung ([[https://www.r-g.de/art/190112-PA-100|190112]])

==== Styrocutter ====

The styrocutter is made with

The styrocutter is operated with a lab power supply in current limiting mode. Set the current to around 2.1A and the voltage to around 20V. The typical resulting voltage will then be around 14V.

==== Lamination ====

There is a description of vacuum pressure process from Purdue University with Mylar

There is an alternative process from Holger Lambertus who does solar flight with peel-ply.

The Mylar way will result in a smoother surface.
