“…The high porosity and shear-weak second phases (MLG) could play important roles in redistributing stress under confined shear in indentation (contact loading), resulting in the suppression of macroscopic (long) cracks. Since high porosity could deteriorate the mechanical properties of the sintered composites, potential approaches (e.g., optimizing MLG content, achieving high density, forming sandwich structure with alternating low and high MLG content layers [42,43]) can be applied to compensate the deteriorated mechanical properties. In order to gain an in-depth understanding of the mechanical behavior and the fracture mechanism of sintered composites, in-situ wedge indentation tests were performed as shown in Figures 6 and 7.…”

Silicon nitride–zirconia–graphene composites with high graphene content (5 wt.% and 30 wt.%) were sintered by gas pressure sintering (GPS). The effect of the multilayer graphene (MLG) content on microstructure and fracture mechanism is investigated by multi-scale and in-situ microscopy. Multi-scale microscopy confirms that the phases disperse evenly in the microstructure without obvious agglomeration. The MLG flakes well dispersed between ceramic matrix grains slow down the phase transformation from α to β-Si3N4, subsequent needle-like growth of β-Si3N4 rods and the densification due to the reduction in sintering additives particularly in the case with 30 wt.% MLG. The size distribution of Si3N4 phase shifts towards a larger size range with the increase in graphene content from 5 to 30 wt.%, while a higher graphene content (30 wt.%) hinders the growth of the ZrO2 phase. The composite with 30 wt.% MLG has a porosity of 47%, the one with 5 wt.% exhibits a porosity of approximately 30%. Both Si3N4/MLG composites show potential resistance to contact or indentation damage. Crack initiation and propagation, densification of the porous microstructure, and shift of ceramic phases are observed using in-situ transmission electron microscopy. The crack propagates through the ceramic/MLG interface and through both the ceramic and the non-ceramic components in the composite with low graphene content. However, the crack prefers to bypass ceramic phases in the composite with 30 wt.% MLG.

“…The weak interlayer is often made of graphite, boron nitride (BN), and other materials, while the strong interlayer is often made of ZrO 2 , Al 2 O 3 , and other materials 6,88 . The preparation processes of layered ceramic bodies mainly include tape casting, freeze casting, in situ electrophoretic deposition and additive manufacturing 89,90 . Here, we mainly introduce the tape casting and freeze casting processes.…”

“…The tape casting process to prepare the layered ceramic body requires the following steps: first, the slurry containing ceramic particles, solvents, plasticizers, and adhesives forms a thin tape casting layer under the action of a scraper. Then, the ceramic tape is formed after shearing and drying, as shown in Figure 10a 89 . The ceramic tape prepared with different components of ceramic slurry is sheared, stacked, and compressed to form the green body of layered ceramics.…”

Ceramic materials are widely used in engineering field because of their good physical and chemical properties. The poor mechanical properties of traditional ceramics seriously limit the development of ceramic materials and have attracted extensive attention since its birth. The development of high toughness, light weight, and functional ceramic materials has long been the pursuit of materials scientists. Since ancient times, nature has been the source of all kinds of human technological ideas, engineering principles, and major inventions. The functional structure of biology provides a good research object for the bionic design and preparation of ceramic materials. Therefore, it is necessary to summarize the functional structures and mechanisms in nature and biomimetic preparation technology. The purpose of this review is to provide guidance for the functionalized biomimetic design and efficient preparation of ceramic materials. Some typical functional examples in nature are introduced in detail, and several representative biomimetic preparation methods are listed. Finally, the performance and application status of biomimetic ceramics are summarized, and the future development direction of biomimetic ceramic materials is prospected.

“…The anti-ballistic mechanisms of functionally gradient ceramic are more complicated than monolithic ceramics. At the microscopic level [4][5][6] , the anti-ballistic mechanisms are associated with many factors like the material fabrication processes, interface design, crack deflection, energy absorption and micro-structures. At the macroscopic level [7,8] , the antiballistic performances are related with the functionally gradient structures and internal stress regulation.…”

Functional gradient structure design is one way to improve the anti-ballistic performance of ceramic composite armors. In this paper, the design theory of dual phase hybrid functionally graded ceramics is established. Through the finite element simulation of the anti-ballistic behaviour, three structural effects of dual phase hybrid functionally graded ceramics composite armor are studied: monolithic ceramics (MC), unidirectional functionally graded ceramics (UFGC) and bidirectional functionally graded ceramics (BFGC). The ceramics structure of composite armor is optimized. The simulation results of the optimized structure of unidirectional and bidirectional functionally graded ceramics are better than that of monolithic ceramics, and the weight is lighter. This research can provide theoretical support for the design of functionally graded ceramic composite armor.
