[quote=bradinjax]Is there a simple formula for a lamination schedule for foam core centerboard?
I have spent hours digging around dozens of websites and found some suggestions that seemed close but nothing right on the money.
Background: I want to update the 1977 designed poured foam centerboard for a Stiletto 27 which are fat and short. I have hand shaped a 4'X8'x2" sheet of 10lb foam into three 8ft long boards each 18 inches, 16 inches and 14 inches wide using a NACA 0070 template. Now I need to laminate them and looking for a ballpark schedule. I plan on using the vacuum bag technique with epoxy but not opposed to composite materials.
Worst case scenario I plan on simply adding 2oz layers alternating with a strip of 6oz mat on the chord line until it is heavy enough to not need a downhaul on the board.
Any thoughts?
Thanks in advance
