Hello All
We have been using flat insulated sandwich panels at work recently and its strength is pretty impressive. (50mm expanded polystyrene core with thin steel skin will span sbout 4 meters with a 1 Kpa load!)
It has got me thinking about using composite sandwich panels but substituting the glass for aluminium.
The reasons being isotropic material (Can't lay it up wrong!), can bond to polystyrene (extruded) and has minimal finishing required.
The panels would need to be bonded together (Reading my way through the aluminium bonding topics on HBA)
Please see my construction sketch below. Is this a fundamentally flawed idea? One issue may be that the inner and outer skins don't join?
(This would be a boxy - 'entry level' construction method)
(I posted this in composites as this is where all the foam composite topics are - thought this was the most appropriate place?)
Cheers
David
