“…One of the promising methods of functionalization is To reduce the tendency to aggregate and to increase the adhesion capacity of diorite, it is necessary to functionalize it, which should ensure an effective adhesive interaction at the polymer matrix/filler interface. One of the promising methods of functionalization is the surface treatment of fillers with compounds that provide chemical interaction between the filler and the polymer matrix and reduce polydispersity of the filler, which will enhance the physical and mechanical properties of composites based on them [22,[31][32][33][34]. APTES was used as such a compound.…”

The aim of this paper is to study the effect of a polyfunctional modifier oligo (resorcinol phenyl phosphate) with terminal phenyl groups and a dispersed mineral filler, diorite, on the physicochemical and deformation-strength properties of epoxy-based composites. The efficiency of using diorite as an active filler of an epoxy polymer, ensuring an increase in strength and a change in the physicochemical properties of epoxy composites, has been proven. We selected the optimal content of diorite both as a structuring additive and as a filler in the composition of the epoxy composite (0.1 and 50 parts by mass), at which diorite reinforces the epoxy composite. It has been found that the addition of diorite into the epoxy composite results in an increase in the Vicat heat resistance from 132 to 140–188 °C and increases the thermal stability of the epoxy composite, which is observed in a shift of the initial destruction temperature to higher temperatures. Furthermore, during the thermal destruction of the composite, the yield of carbonized structures increases (from 54 to 70–77% of the mass), preventing the release of volatile pyrolysis products into the gas phase, which leads to a decrease in the flammability of the epoxy composite. The efficiency of the functionalization of the diorite surface with APTES has been proven, which ensures chemical interaction at the polymer matrix/filler interface and also prevents the aggregation of diorite particles, which, in general, provides an increase in the strength characteristics of epoxy-based composite materials by 10–48%.

“…For example, Mingye Wang et al 23 prepared GO-SiO 2 hybrid nanomaterials covered by SiO 2 NPs with diethylenetriamine (DETA) and ethyl orthosilicate (TEOS). The tensile strength, bending strength, and impact strength of 0.1 wt.% GO-SiO 2 /EP composite were increased by 37.11%, 34.35%, and 44.61%, respectively, compared with pure EP.…”

In this research, mercapto‐anchoring graphene oxide (GO) and epoxy‐anchoring SiO2 nanoparticles (NPs) were assembled by mercapto‐epoxy click chemistry to form three‐dimensional (3D) point‐plane structure nanomaterials (GO‐SiO2), and epoxy resin (EP) composites were prepared using the auxiliary thermal blending method. The relationships among surface interfacial interaction, dispersion, and mechanical properties of composites were systematically investigated. The Research finding shows that SiO2 NPs covalently bonding with GO increases interface compatibility and dispersion, which explains epoxy composite strengthening. Compared to epoxy resin, 0.1 wt% GO‐SiO2/EP composite has 38.65%, 36.15%, 44.64%, and 61.61% higher tensile strength, flexural strength, flexural modulus, and impact strengths. The enhancement mechanism of GO‐SiO2 toward EP was analyzed.

“…Consequently, it is authoritative to form a high strength and flame retarded epoxy resin to expand its future applica-tions among the areas that demand outstanding mechanical properties and flame retardancy. Composite fabrication is considered one way to improve the basic and functional properties of epoxy by adding suitable reinforcements and filler material [10][11][12][13][14]. Herein, glass fibres are commonly used as reinforcements to improvise polymer materials' basic strength and performance.…”

The application of nanomaterials as a strengthening agent in the fabrication of polymer nanocomposites has gained significant attention due to distinctive properties which can be utilised in structural applications. In this study, reduced graphene oxide (r-GO) and montmorillonite (MMT) nanoclay were used as filler materials to fabricate hybrid epoxy-based nanocomposites. The synergistic effect of nanomaterials on flammability and mechanical behaviour of nanocomposites were studied. Results revealed that the addition of nanofiller showcases 97% and 44.5% improvement in tensile and flexural strength. However, an increment in the percentage of filler material over 0.3% exhibits a decremental mechanical property trend. Likewise, the addition of nanofiller increases the nonignition timing of the glass-fibre-reinforced epoxy composites. Fracture surface morphology displays the occurrence of the ductile fracture mechanism owing to the presence of hybrid fillers.
