I think it's some kind of shielding effect, maybe even a one-shot guaranteed block of any attack, no matter how powerful. That would explain why Jaune was able to stop Cardin's punch (and from Cardin's reaction, he'd effectively punched a solid panel of armour plate) but that it didn't stop the very next hit coming his way.
