A study is made of glass/glass-ceramic bilayer as a model homogeneous/heterogenous laminate. The underlying objective is microstructural design of ceramic layer systems with optimum mechanical properties, alternating hard layers, for wear resistance, with tough layers for fracture resistance. Mica flakes in the glass-ceramic layer inhibit the propagation of well-developed intrusive cracks, by bridging; these same flakes render the structure susceptible to distributed damage, by providing a discrete weakness at the microstructural level.
