Strength evolution laws in curing of solvent-welded polymers.

This paper reports the scaling laws to describe the time-evolution behavior of solvent-mediated strength at the interface between two identical thermoplastic polymers below the glass-transition temperature. Our results suggest that the evolution scales as sqrt[t], where t is the curing time. It depends on the time evolution of interfacial stiffness and toughness, each of which scales as sqrt[t].
