The feasibility of designing artificial bioinspired ceramic composites with very high crack resistance is demonstrated by bounding of zirconium oxide sheets (70 μm thickness) with only a few micrometers thin adhesive layers. The small amount of organic adhesive (about 5.8 vol%) provides the composite with a crack resistance exceeding 18 MPam 1/2 , which is about four times as high as that of the basic ceramic material.
