Description of the fiber wing design, analysis and construction.

• Core Material: BASF Styrodur 5000 CS XPS (50 kg/m3)
• Epoxy Resin L + Hardener EPH 181 90 Minuten
• R&G Glasgewebe 49g/m2, Leinwandbindung (190105)
• R&G Glasgewebe 80g/m2, Köperbindung (190112)

The styrocutter is made with

• Kanthal Nikrothal 80 Widerstandsdraht, Diameter 0.5mm, 5.55 Ohm/m

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.
