“…Studies have elucidated that the strength of MMCs can be enhanced by the addition of uniformly distributed nanoscale carbonaceous particulates to the metal matrices. Carbon nanomaterials, such as single-walled carbon nanotubes (SWCNTs), multi-walled carbon nanotubes (MWCNTs), and graphene nanoplatelets (GNPs), exhibit great potential as nano-reinforcing materials in MMCs because of their high surface areas, extraordinary mechanical strength, and chemical stability [ [321] , [322] , [323] ]. Table 11 summarizes the characteristics and mechanical properties of various carbonaceous reinforcement materials.…”

Biodegradable metals (BMs) gradually degrade in vivo by releasing corrosion products once exposed to the physiological environment in the body. Complete dissolution of biodegradable implants assists tissue healing, with no implant residues in the surrounding tissues. In recent years, three classes of BMs have been extensively investigated, including magnesium (Mg)-based, iron (Fe)-based, and zinc (Zn)-based BMs. Among these three BMs, Mg-based materials have undergone the most clinical trials. However, Mg-based BMs generally exhibit faster degradation rates, which may not match the healing periods for bone tissue, whereas Fe-based BMs exhibit slower and less complete in vivo degradation. Zn-based BMs are now considered a new class of BMs due to their intermediate degradation rates, which fall between those of Mg-based BMs and Fe-based BMs, thus requiring extensive research to validate their suitability for biomedical applications. In the present study, recent research and development on Zn-based BMs are reviewed in conjunction with discussion of their advantages and limitations in relation to existing BMs. The underlying roles of alloy composition, microstructure, and processing technique on the mechanical and corrosion properties of Zn-based BMs are also discussed.

“…Among them, ZrO 2 nanoparticles improved the overall properties such as high strength and toughness, high wear resistance as well as good chemical resistance of nanocomposites . Ahmad et al reported that the radial surface modification of MWCNTs by ZrO 2 nanoparticles not only reduces the strong van der Waals force of attraction between adjacent MWCNTs but also breaks their cluster that enhances dispersibility, interfacial bonding, and mechanical performance of hybrid nanocomposites. Therefore, it is an attractive nanofiller along with MWCNTs that can enhance the mechanical strength and fracture toughness of polymer nanocomposites.…”

Although carbon nanotubes (CNTs) have displayed great potential for enhancement of multifunctional properties of a polymer matrix, still incorporation of CNTs with the polymeric matrices requires further improvement in terms synthesis, processing, functionalization etc. In this study, we decorated the surfaces of multi‐walled CNTs (MWCNTs) by zirconium dioxide (ZrO2) nanoparticles to fully utilize former's remarkable mechanical properties, and then MWCNT/ZrO2‐based hybrid epoxy nanocomposites (MNCs) were synthesized via a novel ultrasonic dual mixing (UDM) technique. The fracture strength and toughness of prepared MNCs were studied using a 3‐point (3‐P) single edge notch bending test. The surface morphology and fracture mechanisms were examined through field emission scanning electron microscope images of the fracture surfaces of samples of MNCs. Apart from experimental investigations, the mechanics of materials (MOM) and finite element (FE) models were also developed to predict the effective elastic properties of two‐ and three‐phase MNCs. The mechanical response of MNC‐based beams was studied using 3‐P bending test via FE simulations and the numerical predictions are found to be in good agreement with the experimental results with maximum discrepancy of ~6% at 1 wt% loading of hybrid nanofillers. Our results also reveal that the fracture toughness of MNCs is improved by ~31% compared to the neat epoxy when 1.0 wt% loading of MWCNT/ZrO2 hybrid nanofillers is used to fabricate MNC.

“…The development of alumina hybrid ceramic nanocomposite materials with enhanced comprehensive performance (hardness, fracture toughness, strength, electrical conductivity, thermal conductivity, and thermal stability) is in its early stages and it is expected to continue attracting the interest of the scientific community. Diverse consolidation techniques [151,152,153,154] were used to consolidate alumina hybrid nanocomposites; this review investigated the development of alumina hybrid nanocomposites while using the spark plasma sintering method. These composites have showed their potential as advanced materials that are suitable for new and unique applications.…”

Although ceramics have many advantages when compared to metals in specific applications, they could be more widely applied if their low properties (fracture toughness, strength, and electrical and thermal conductivities) are improved. Reinforcing ceramics by two nano-phases that have different morphologies and/or properties, called the hybrid microstructure design, has been implemented to develop hybrid ceramic nanocomposites with tailored nanostructures, improved mechanical properties, and enhanced functionalities. The use of the novel spark plasma sintering (SPS) process allowed for the sintering of hybrid ceramic nanocomposite materials to maintain high relative density while also preserving the small grain size of the matrix. As a result, hybrid nanocomposite materials that have better mechanical and functional properties than those of either conventional composites or nanocomposites were produced. The development of hybrid ceramic nanocomposites is in its early stage and it is expected to continue attracting the interest of the scientific community. In the present paper, the progress made in the development of alumina hybrid nanocomposites, using spark plasma sintering, and their properties are reviewed. In addition, the current challenges and potential applications are highlighted. Finally, future prospects for developing alumina hybrid nanocomposites that have better performance are set.
