“…The binder molecules repeat the layer morphology of the filler, as shown in Figure 4b-c, which is apparently one of the facts explaining the significant increase in the properties of epoxy composites in the presence of an active filler, diorite. The analysis of the literature data has shown that the addition of dispersed fillers affects the kinetic characteristics of the polymerization reaction of the epoxy composition during curing as well as the formation of the phase structure of the composite material [6,13,[23][24][25][26][27].…”

“…The effect of the addition of a filler on the properties of the polymer is determined by many factors: the chemical nature of the polymer and filler, the nature of the filler surface, the size and shape of its particles, the ability to form their own structures, a change in the conformational set of macromolecules and the structure of the polymer itself. The added fillers with different quantitative content have different effects on the structure of polymers [ 10 , 11 , 12 , 13 ].…”

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%.

“…An interesting potential filler for biocompatible innovative epoxy composites is zeolite and its varieties. There are researches on the effect on epoxy polymers of montmorillonite [14,15,25], clays and brick dust [3,16], aluminum oxide [10,20,21], pyrophyllite [11], brick powders [3,16], natural zeolites [18], bentonite [22], copper [26,27]. These issues are dealt with by teams led by Danchenko & Barabash [19][20][21], Erdogan [18], Choi & Leе [15], Burmistrov & Mostovoy [16], Starokadomsky [3,10], Borisov and others [25], Kahramanov & Allahverdieva [26,27].…”

A study on the complex effect of the microdisperse fraction of zeolite (50 wt%) on the strength and stability of the polyepoxide composite. The results indicate the prospects of using zeolite to increase the compressive strength and Young's modulus, adhesion to steel, microhardness of composites. It is established that the filling significantly increases the resistance to abrasion, aggressive liquids (acetone and peroxide solutions), fire resistance.

“…The effectiveness of using brick dust as a cheap, active filler of an epoxy polymer, which provides an increase in both physicochemical and mechanical properties, was proved in [ 16 , 17 ]. It was found that the addition of 30–50% by weight of brick dust has an effect on the processes of the structure formation and the structure of the epoxy composite, thus providing an increase in bending and compression strength, as well as a significant increase in impact strength, in comparison with an unfilled epoxy composite.…”

The conducted studies have proven the possibility of the directed control of operational properties of epoxy composites, due to the addition of finely-ground ocher into their composition, and the use of microwave modification of the epoxy composition. The rational content of ocher as a modifying additive (0.5 parts by mass) and a filler (75 parts by mass) of the epoxy composition has been selected, which ensures the improvement of the studied complex of physical-mechanical properties. It has been proven that ocher affects the structure formation processes and the structure of the epoxy composite, thus increasing its thermal, heat and fire resistance. During the research, the application efficiency has been proven, and the optimal parameters of the microwave modification (power—350 W; duration—30 s) of epoxy compositions filled with ocher, which increase physical-mechanical characteristics of composites, have been selected.
