“…The thermal degradation temperature increased at 15% and 50% of silica with the tremendous weight loss was linear and decrease compared to silica loadings. This analysis enhanced thermal stability and improved the arrangement of the nanocomposites at elevated temperatures 49,50 . The presence of a silica network is accountable for a decrease in all uncoupled silica‐epoxy nanocomposites systems.…”

This research article describes the results of nano-silica composites filled with different epoxy contents containing nano-SiO 2 particles from (5-25 wt%). Reinforcing hybrid composites enhance thermal and mechanical properties to achieve vital and sustainable products. Silica-based nanocomposites with high purity were prepared and used for the surface modification of nanosized silica particles. The surface structure's composition and physical properties of modified nano-SiO 2 particles were characterized through Fourier transferred infrared spectrometer, X-ray photoelectron spectroscopy, thermogravimetric analyzer, and scanning electron microscopic. Silica-based nanocomposites were prepared by incorporating of modified nano-SiO 2 as an enhancing filler.The morphology of fracture surface and dynamic mechanical properties were investigated. Results showed that the silica-based epoxy nanocomposites are bearing a long chain structure that could improve the compatibility of silica nanocomposites with epoxy resin and contribute to a better dispersion state in the matrix, which enhanced the overall performance of epoxy-cured products.

“…[ 142 , 143 , 144 ] This composite material combines the excellent properties of various components, and the introduced metal elements can refine the grain structure by solution segregation and phase separation effect. [ 145 , 146 , 147 , 148 ] However, it is still a challenge for the doped metal elements to be uniformly distributed in the matrix and form ultra‐fine structures. Taking the W–Cu matrix composite as an example, the homogeneous and compact W–Cu alloy has excellent electrical, thermal and mechanical properties.…”

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.

“…It was reported the fine-grained W–Cu composites with a grain size of ~1 μm showed higher high-temperature strength than the commercial counterparts with a grain size of ~8 μm [ 27 ]. In addition, ultrahigh high-temperature strength was achieved in nanostructured W–Cu–Cr–ZrC composites [ 28 ]. The wear resistance of nanostructured W–Cu composites was also largely improved [ 29 ].…”

W–Cu composites are commonly subjected to coupled multiple fields in service, which imposes high requirements on their overall performance. In this study, the ultrafine-grained W–Cu composite was fabricated using the combination of electroless plating and spark plasma sintering. The wear resistance and high-temperature compressive properties of the ultrafine-grained W–Cu composite were investigated and compared with those of the commercial coarse-grained counterpart. Moreover, the underlying strengthening and wear mechanisms were also discussed. Here we show that the ultrafine-grained W–Cu composite exhibits superior integrated mechanical performance, making it a potential alternative to commercial W–Cu composites.
