Summary: This article reviews recent advances in ternary diglycidyl ether of bisphenol A epoxy nanocomposites with nanoparticles and other modifiers, focusing on their mechanical and thermal properties. Various single toughening agents, in solid or liquid states, have been incorporated to enhance the properties of epoxy resins. The use of two appropriate modifiers for hybrid composites can potentially have a synergistic effect on performance properties. The study mainly focuses on widely used nanoclays with modifiers in both liquid and solid states. Some studies have confirmed the synergistic effect in the performance properties of epoxy matrix, but ongoing research is still exploring other nanoparticles and modifiers to further enhance the mechanical and thermal properties of epoxy resins.

Summary: Using UFMs containing an oxidizable oil phase modified by APTES has shown to enhance the toughness of epoxy composites. The presence of functionalized UFMs resulted in improved fracture toughness and morphology compared to non-functionalized UFMs, with part of the microcapsule shell remaining in the matrix after fracture.

Summary: Hierarchical structure composites with carbon fiber reinforced polymer (CFRP) interleaved by nanoscale core-shell rubber (CSR) and microscale short carbon fiber (SCF) were fabricated. The hierarchical structure exhibited superior interlaminar toughening efficiency. The multi-phase interleaved CFRP composite had significantly higher mode-I and mode-II critical energy release rates (GIC and GIIC) compared to unmodified samples, while maintaining the tensile properties and glass transition temperature (Tg). The study also revealed the synergistic toughening mechanisms in SCF/CSR interleaved CFRP composites.

Summary: The study investigated three preparation methods of cold-mixed epoxy bitumen (CEB) for steel bridge deck pavements, finding that the methods significantly affected the performance of cured CEBs. The three-component method achieved acceptable mechanical performance, while the two-component methods required the curing agent to be mixed with bitumen for satisfying microstructures.

Summary: The study found that EP can effectively enhance the mechanical strength of composites, with EP/HTPU1 exhibiting the best tensile properties of the EP matrix and CF/EP/HTPU2 showing the highest longitudinal tensile strength. The microstructure after curing and the interfacial adhesion between matrix and fibers strongly affect the tensile properties of composites.

Summary: This paper reviews the influence of hard segment chemical structure on the properties of thermoplastic polyurethanes based on dimer fatty acid soft segments and on their blends with bitumen. The results indicate that phase separation quality depends on the choice of hard segments and their ability to self-organize within crystalline structures. Morphology analysis and swelling measurements demonstrate that the quality of phase separation and compatibility with bitumen have a significant impact on the polymer's swelling.

Summary: The aim of this study was to develop a newly synthesized ether-linked N, N-tetraglycidyl diamino-diphenyl ether (TGDDE) epoxy resin incorporated with amine-functionalized zinc oxide (F-ZnO) to enhance its mechanical and thermal properties. The TGDDE epoxy resin was synthesized and characterized, and the F-ZnO was synthesized using a condensation method. The mechanical and thermal behavior of the TGDDE epoxy matrix and nano-composites were analyzed, and the results showed that the inclusion of 1 wt% of F-ZnO nanoparticles achieved the highest improvement in mechanical properties, thermal stability, and DMA analysis.

Summary: In this study, Al2O3-based ceramics were fabricated by adding zirconia sol into natural bauxite powder. The addition of zirconia sol accelerated grain boundary migration during sintering and formed numerous intracrystalline pores, leading to improved fracture toughness and flexural strength. However, the formation of intracrystalline pores was accompanied by the formation of large intercrystalline pores, which were detrimental to the mechanical properties of the materials.
