- A new stress-based criterion of interfacial failure in micromechanical tests - critical interfacial normal stress, or adhesive pressure - is proposed. The new criterion has two important advantages: it follows the actual mechanism of crack initiation (in tensile Mode I) and allows to relate interfacial strength to such fundamental physical quantity as thermodynamic work of adhesion. The adhesive pressure values have been experimentally determined for several polymer/fiber model composites; it appeared to linearly depend on the work of adhesion measured independently. The model based on splitting the work of adhesion into the dispersion and acid-base contributions describes the observed relationships.
