Strength of Tape Cast and Laminated Ceramics

Monolithic A1 2 O 3 ceramic laminates were fabricated via a tape casting process. The strength of single tapes was compared with that of laminates, using biaxial flexure tests. The fracture stress was similar. However, the laminates presented a lower Weibull modulus. The feasibility of eliminating or diminishing void‐type flaws present in the green tapes was also assessed. To this end, tapes were first punctured, then laminated and sintered, …
