“…Liu [ 82 ] described the influence mechanism of the laminated structure on fracture toughness of composite materials from a new theoretical perspective and obtained transverse crack growth and surface intersection according to indentation theory of Marshall, as shown in Figure . [ 82 ] The volume of the plastic zone decreased with the increase of fracture toughness; the height of the plastic zone and the length of the lateral crack decreased, indicating that the laminated structure had a positive effect on the fracture toughness and a negative effect on the hardness of the composite.…”

The design of lamination structure based on bionic shell pearl layer is a successful method for toughening ceramics. Lamination with strong bonding interface have been used to improve the mechanical property and low fracture toughness of ceramic cutting tools. Based on the idea of demand‐design‐preparation‐analysis‐failure, the development and research progress of laminated ceramic tools are reviewed in this paper. The research status of design, interlayer diffusion reaction, residual stress, toughening mechanism and crack propagation path of the biomimetic laminated ceramic composite tool materials are mainly introduced. The major topics of current research include the creation of material systems, the evolution of microstructure, and the assessment of macroscopic mechanical properties. The entire mechanical properties of laminated ceramic tools are significantly influenced by the multi‐composition design of the ceramic material system and the optimization design of structural parameters of layer number and layer thickness ratio. However, the research on the practical cutting application of laminated ceramic tools is limited. Cutting tool wear characteristics vary between laminated and homogeneous ceramic tools. The development of useful laminated ceramic cutting tools can greatly benefit from the study on failure mechanisms of laminated ceramic tools.This article is protected by copyright.
