Rate-dependent fracture at adhesive interface

Article Abstract:

The fracture of a polymer-glass interface model system was investigated using Schallamach's theory of rate-dependent bond dissociation. The model system used consists of an elastomeric film of poly(dimethylsiloxane) that is chemically bonded to a silanized glass substrate. The fracture energy of the interface was found to be consistent with Schallamach's theory. Results also showed that the equilibrium threshold toughness of an interface is the product of the number of polymer chains and the dissociation energy of a single bond.
