Europa-List: Bulkhead Material

[Tony Renshaw <tonyrenshaw268@gmail.com>]

> Hi,
 Can someone please remind me of the name of a material I can buy from ACS t
hat can be used as a substrate for a small reinforcement bulkhead within a w
ing fairing? I don't mean foam, if someone with a sense of humour might sugg
est, but something cloth on both sides will stick to,well,,and ideally is on
ly 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 thin
k there is a purpose specific board.
