Over the past decade, a new family of ceramic matrix composites has been developed from the incorporation of homogeneously dispersed graphene-based fillers (graphene nanoplatelets/GNP, graphene oxide sheets/rGO or graphene nanoribbons/GNR) into the ceramic matrices. These composites have shown a significant increment of their fracture toughness accompanied by other electrical and thermal functionalities, which make them potentially attractive for a wide range of applications. Here, the main methods for testing the fracture toughness of these composites are described, then the principal observations on the reinforcing mechanisms responsible for this improvement are briefly reviewed, and we discuss the relation with graphene platelets type, morphology and alignment. This article is part of the theme issue 'Nanocracks in nature and industry'.

“…The stress value nearly remained unchanged in the material's center and decreased at the edge. [ 17 ] As shown in Figure , [ 30 ] the radial stress value was prone to abrupt change near the edge of laminated materials. To select the appropriate size of the sintered die, the edge mutation effect of residual stress in the sintering process should be considered.…”

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.
