Hi,
Can someone please remind me of the name of a material I can buy from ACS that can be used as a substrate for a small reinforcement bulkhead within a wing fairing? I don't mean foam, if someone with a sense of humour might suggest, but something cloth on both sides will stick to,well,,and ideally is only 1/8-1/4" in thickness. Thanks in anticipation.
Regards
Tony Renshaw.
P.S. It's just dawned on me, we have used balsa as such a medium, but I think there is a purpose specific board.

How about flex core, it’s the stuff used to make the rear bulkhead, as you already said balsa wood will bond well too and you can shape it easily

Tony,

Polyurethane rigid foam sheet is usually what is used for bulkheads, etc. Probably 1/8 or 1/4 inch thick. It is extremely easy to shape with hand tools (saw, knife, abrasives, etc.), but do not hot-wire as it produces cyanide gas when vaporized.
If you can not get the thickness material you need from ACS, you can try McMaster-Carr. Shipping weight for the material isn’t an issue but packaging bulk is.

Tony
not sure what you are trying to achieve. I always made the fairings press lightly against the fuselage
so that there was no gap, and made them flexible enough to move with the bending of the wing.
Also filled the fuslage around the edges of the fillets to give a smooth transition from fillet
to fuselage.

Why are you averse to foam? Lastafoam (I believe is polyurethane)
0.2inch thick should work well for this. Aircraftspruce has it for $36
for a big sheet.
