“…The increase is due to the functional groups of the modifier that react with one of the components of the curing system. 8,20 In the case of ER modification with TCP plasticizer, the increase in TCP share leads to a decrease in strength properties of the composite. It was observed that the tensile and bending strength decreases as TCP content increases from 10 to 20 % wt., while there is a decrease and increase in bending strength.…”

“…As it is known, the mechanical properties of AF/ERs depend not only on the strength properties of the fibers and matrix, but also on the nature of the fiber surface and the mechanisms of load transfer from matrix to fiber at the interface. 7 Therefore, modern literature reports quite a lot of studies [8][9][10][11] on ways to improve the mechanical characteristics of AF/ERs and currently there is a search for optimal technologies. For example, they can consist of modifying the polymer matrix, various treatments of the fiber reinforcement, combination of reinforcement, etc.…”

Polymer composites, in particular aramid-epoxy composites, are widely used in fields such as aerospace, transportation, electronics, etc. due to their excellent mechanical and dielectric properties. This article presents studies of modification and combined reinforcement on the mechanical properties of aramid-epoxy composites. The influence of matrix (epoxy resin) and reinforcing filler (aramid fabric) mass ratio and ways to increase strength characteristics and impact toughness of the composite were studied. Comparative results for composites made by vacuum forming and vacuum infusion methods are presented. Mass ratio of reinforcing filler and matrix varied in the range of 50:50%, 60:40%, 65:35%, and 75:25%. It was found that modifying epoxy resin with polyurethane rubber plasticizer, together with combined reinforcement of aramid fabric/aramid roving, resulted in composite strength up to 720 MPa and impact toughness of 426 kJ/m2. Modification of epoxy resin with tricresyl phosphate leads to composite strength up to 710 MPa and impact toughness of 475 kJ/m2. Thus, it is shown that modification and combined reinforcement of aramid-epoxy composites are the most effective methods to increase strength and adhesion to epoxy resin.

“…Various plasticizers or thermoplastics are most often used [6] as modifiers of epoxy resins. Oleic acid, oligoxypropylene glycol and dchlorobutyl esterβchloropropionic acid were studied in the work [7] as the plasticizers for ED20 epoxy resin on a polyethylene polyamine (PEPA) hardener.…”

“…From the works [6][7][8]10], it follows that the modification of epoxy resin with plasticizers and thermoplastics is promis ing both for increasing the toughness and strength of the com posite. However, these works deal mainly with the widely used ED20 "cold" hardening epoxy.…”

“…To increase the toughness, the following modifying addi tives were used in the experiments: plasticizers such as tricresyl phosphate (TCP), trichloro ethyl phosphate (TCEP) and glycidyl methacrylate (GDMA) [6] in a liquid state at a room temperature; thermoplastics such as polysulfone (PSF), polycarbonate (PC), polystyrene (PS) and high impact polystyrene (UPS). These polymers are in a solid state at a room temperature; when they are heated, they transform into a highly elastic or viscous flow state, and they have rather high temperatures of a viscous flow and decomposition.…”

stuDy on the effect of plAstIcIZers AnD therMoplAstIcs on the strenGth AnD touGhness of epoxy resIns purpose. To increase the strength and toughness of epoxy resins of "cold hardening" and "hot hardening" by using modified plasticizers and thermoplastic polymers. Methodology. Epoxy resins of "cold hardening" of ED20 and "hot hardening" of Etal InjectT, modified with three types of plasticizers and four types of thermoplastic polymers, were investigated. The toughness and compressive strength of unmodified and modified resins were determined with the help of the Charpy impact test at various modifier contents. findings. Among all studied plasticizers, tricresyl phosphate has the most significant effect on the strength and toughness of both types of resins. The best combination of strength and toughness of ED20 resin is obtained with 5 % tricresyl phosphate con tent, whereas its higher content reduces the strength of the material. For Etal InjectT, high values of these properties are obtained with 15 % tricresyl phosphate content, whereas adding a smaller amount of a modifier does not change the material strength. The modification with thermoplastic polymers has a less obvious effect on the properties of epoxy resins than the modification with plasticizers does. The most effective additives to ED20 are hightemperature polycarbonate (5 %) and polysulfone (10 and 15 %), the addition of which causes a simultaneous increase in both properties. A significant increase in the toughness of Etal InjectT is observed by adding 5-15 % polycarbonate, but the strength of the resin hardly changes. The complex modification of resins with a mixture of plasticizer and thermoplastic leads to a decrease in the toughness and compressive strength of both types of resins. originality. When the polymer mixture hardens, plasticizer molecules dispersed into the environment of epoxy macromole cules weaken the rigid spatial crosslinking of macromolecules and make them more active. As a result, toughness increases; in certain cases so does resistance due to directed reorientation of macromolecules under deformation. The change in mechanical properties of epoxy resin when modified with thermoplastics is defined by the bonding strength of the resin and dispersed particles of thermoplastic polymer as well as by the degree of heterophase of the produced mixture. practical value. The results of changing the mechanical properties of epoxy resin while being modified with plasticizers and thermoplastics can be used to produce impactresistant composite materials for structural purposes, including those for aviation and spacerocket technology.

The physical-mechanical and tribological properties of anti-friction carbon fiber plastic UGET based on low-modulus carbon fabric “Ural T-15R” have been studied in order to increase the magnitude of the ultimate deformation and reduce the elastic modulus through the use of a modified thermosetting matrix ET-4 instead of the traditionally used ET-2.Modes of polymerization and of heat treatment of epoxy binders were selected considering the results of the experiments. Prototypes of prepregs were obtained by solution impregnation on the UPST-1000M line and then processed into PCM by hot pressing. Laboratory samples were made and physical and mechanical tests were carried out to determine the ultimate strength under compression, shear and bending stress under destruction, as well as Charpy impact strength. Steel 20Kh13 and oxidized titanium alloy PT-3V were used as counter body rollers to determine carbon fiber tribosets.It was shown that carbon fiber samples based on chemically modified binder ET-4 with two-stage polymerization and heat treatment mode in the range of 90°C to 180°C both have better physical-mechanical and tribotechnical properties, in contrast with the analogue with a three-stage mode and carbon fiber carbon heat at friction over 20Kh13 steel and oxidized titanium alloy PT-3V.
