Fibreglass Layer Query

I'm a designer and manufacturer of surfboards, and i'm working on a few projects in which i'm trying to minimise weight without sacrificing strength, particularly compression strength. Currently, the deck of my boards use 2 layers of 4oz (~113g) woven S Glass with PE resin. I have an idea to use one layer of biaxial 320g fibreglass with epoxy resin on the deck. From what I've read, biaxial glass is more effective in distributing compressive loads across the laminate, so will this construction result in a strong but compression resistant laminate? Both constructions are laminated around a PU foam core...

The fibres are running much straighter and flatter so tensile strength is higher, one layer of biaxial is effectively two layers of uni directional at 90 degrees. It's more awkward to work with than woven especially with wet lay as the fibres are only held together with intermittent cross stitching. Surface finish won't be as flat either so may require more finishing work compared to woven. Warren Carbon Copies Ltd Edited 11 Years Ago by wozza
