Let's not praise cork too much, it might be nice and cheap but it has a pretty high density. The fact that parts made with soric aren't any lighter doesn't make cork great, it just shows what a shitty choice materials that soak up resin like soric are for thick parts. Compared to other core materials (like rohacell, airex, polyurethanes, balsa, styrofoams etc. and of course honeycombs) the cork sandwiches are very heavy. I have a customer who manufactures wind turbines. In the layup schedule for the blades he specifies Soric. I would love to hear what you would suggest he should be using?
Requirements: Conforms easily to compound curves.
Withstands high crush forces (hard points)
Acts as an excellent flow medium.
Easy to work with and requiring no special tools
Comparable on price.
Then I can tell him what he should be using instead of the "shitty" Soric he currently specifies in his award winning design.
Thanks in advance Warren.
