I'll be the first to post in composites...
I am looking for a lower cost option to Airex foam (R90) for a seaplane hull. I have looked at Urethane and Klegecell (PVC). It must be closed cell. All, except Airex, will delaminate when the foam fractures from impact. I want to be able to walk on it also.
Perhaps a non-glass resin system with an Airex type foam would give a stiff surface without the "glass" fracturing effects. Adding layers is not possible because there is a lot of surface to walk on, and the weight would sink the design.
Suggestions?
