Layup and epoxy for the 68 carbon

Layup and epoxy for the 108 glass + 93 carbon D-box wing (not made)

Thoughts about a very light layup (not made)

FYI: You need about 1,5 gram epoxy pr. 1 meter 24 NF carbon tow.

The outer layer (25 g/m^2 glass + 68 g/m^2 carbon/kevlar cloth)

	Top	Bottom
Leading edge	12g	12g	Optional: (This is 12 gram epoxy with micro balloons to fill the very curved part of the leading edge)
Glass cloth 25 gr	16	16
Carbon/kevlar 68 gr	44	44
for the brush	5
Total	77g	72g
	(56+21)	(52+20)

The numbers in the paragraphs are theparted weights (resin + hardener).

Epoxy for the main spar + inner cloth + other things:

	Top	Bottom
Inner cloth (25 g/m²)	16g	16g
Mainspar_#2	51g	44g
Glass tape at the hinge line		9g
Total	67g	69g
	(48+19)	(50+19)

Use it all but don’t use more.
