“…The magnification observation further reveals that the crack expansion paths are repeatedly deflected by resin/fabric layers, this behavior could consume more fracture energy per unit length to prevent risky brittle fracture behaviors. 32,33 As summarized in a diagrammatic sketch for the mechanical mechanisms in Figure 7, the excellent mechanical properties of this multilayered composite are correspondent to its bioinspired shell-like structure, the presence of resin/fabric content, and appropriate bonding state between layers, and the crack deflection, interfacial debonding and fiber pull-out are proved to be the main strengthening and toughening mechanisms.…”

Ceramic materials with high strength, toughness, and excellent impact resistance are urgently required for many structural applications, but these mechanical properties are difficult to achieve in traditional ceramic tiles due to their inherent brittleness. Inspired by the specific structure of shells, the multilayered ceramic tile/Kevlar fabric composite with a bio‐inspired shell structure was successfully fabricated via a surface hydroxylation followed by simple hot press process. It is found that the composites have representative step‐like fracture behaviors rather than brittle fracture, which has been proven to possess a better ability of mechanical performance and noncatastrophic failure behavior compared to same‐thickness ceramic tile. Specifically, the bending strength, fracture toughness, and fracture work of the composite with a 15‐tier structure come to 836.5 ± 12.5 MPa, 14.6 ± .2 MPa·m1/2, and 7228.8 ± 108.4 J·m1/2, which are even better than those of reported advanced materials. Such fracture‐resistant behaviors are correspondent to the strengthening effects of the crack deflection, interfacial debonding, and fiber pull out, accompanied by bio‐inspired structure and appropriate bonding state between brittle or ductile layers. This resin or fabric content can be used as well as the slip systems to transfer the internal stress in time to consume more fracture energy per unit length and prevent risky brittle fracture, while carrying loads. We expect these findings to provide vital guidance for promoting the applications of traditional ceramics in bio‐inspired high‐performance composites for actual ceramic manufacturers.

Material extrusion (ME), one of the most rapidly developing additive manufacturing techniques, has been widely used in the field of aerospace, medical, industrial design, and so on. Since the working environment is increasingly complex, it is urgent to study the ME products' dynamic performances to determine their reliability. In this article, a finite element theoretical model of ME thin plate was established with the porosity defect taken into account. A modal test system was set up and the multiple‐input single‐output method was used to obtain the measured data. The scanning electron microscopy (SEM) analysis on the samples confirmed that the dynamic characteristic was improved as the extrusion temperature increased. In addition, the sensitivity analysis was carried out on the model to predict how the samples' elastic modulus, Poisson's ratio, and density affect their dynamic characteristics. The results show that the proposed model is reliable to give accurate predictions on the dynamic characteristics of ME thin plates. With the increase of extrusion temperature, the samples' natural frequency will increase, and the vibration response will decrease. The sensitivity analysis indicates that increasing elastic modulus or Poisson's ratio can increase the natural frequency of ME thin plate but decrease the vibration response. While increasing the density will decrease both the natural frequency and vibration response.

“…Since the traditional ceramic materials have low fracture toughness and tensile strength, which would give rise to a sudden plastic deformation when carrying heavy loads [10], the composite materials such as ceramic matrix composites (CMCs) that would notably enhance the ceramic toughness attract significant research attentions in recent years. The CMC material is composed of two phases, where the matrix phase is reinforced by doping phases utilizing fibers or nanoparticles (NPs) [11,12]. These multiphase nanoparticles undergo sintering, resulting in a distinctive distribution structure within the CMC components, endowed with enhanced toughness and strength [13,14].…”

The reinforced ceramics, known as ceramic matrix composites (CMCs), is playing an important role in modern advanced industrial applications. However, the fabrication of CMCs with both high toughness and high stiffness, which are normally considered mutually exclusive, is still challenging. Here, we develop a gradient property SiOC composite film reinforced with nanoscale tungsten-based particles using a novel avenue of the integration of hybrid nanoparticles inkjet printing and selective laser sintering. Mechanical results of SiOC-WOx films exhibit the stiffness-toughness co-enhancement, including a twofold improvement in hardness and modulus, and an over 3.8-fold better fracture toughness performance than its matrix. Moreover, owing to the metal-to-ceramic gradient properties, the films exhibit interfacial bonding strengths up to 86.6 MPa and operate stably even at 1050 ℃. Characterization results show that the excellent mechanical and interfacial performance is attributed to the significant gradient composition and uniformly dispersed self-assembled nanoscale reinforcing particles. The success of SiOC-WOx CMC films demonstrates the potential to accelerate the discovery of revolutionary nanocomposites using hybrid nanoparticles and bottom-up additive manufacturing processes.
