    The aim of this work was preparation of alumina and zirconia laminates containing zirconia or alumina micro-fibres inside the inter-layer interface. Electrophoretic deposition was performed from concentrated isopropanolic suspensions stabilised by monochloracetic acid. The electrophoretic deposition was interrupted at certain time intervals and layer of micro-fibres was then deposited. By this method a laminate consisting of ceramic layers of thickness about 50 micrometers separated by thin layers of micro-fibres was prepared. A method for in-situ monitoring of deposited amount of mixture of particles and fibres mass was applied to control deposition kinetics. Two different approaches for micro-fibres length treatment were applied: pre-milling and ultrasonification of suspension containing micro-fibres. Applying the optimised procedure the alumina laminates were prepared consisting of fibres in the interlayer boundary affected dramatically fracture response of these materials. This type of material exhibited potential of the crack trapping and deflection even when very small amount of micro-fibres was used.
