Bonding steel sheet to foam core
Bonding steel sheet to foam core
(OP)
I am planning to make a composite test piece using 4130 N steel sheets, .025 thickness, bonded to a foam core using a room temperature cure epoxy, Any suggestions on preparing the steel surface would be appreciated.





RE: Bonding steel sheet to foam core
4130 will flash rust if any moisture is present, this will reduce your bond strength.
