Представлены результаты исследования свойств гистерезисных процессов, которые легли в основу математических формулировок двух феноменологических моделей. Эксперименты проводились с двумя диссипативными системами: гасителем колебаний маятникового типа, а также реовискозиметром, где в качестве рабочего тела использовалась электрореологическая суспенз...

When creating elastomeric composites, structures and products made from such materials, considerable attention is paid to environmental issues, as well as to improving economic efficiency and energy efficiency in its production. In this regard, the development of new types of strengthening highly dispersed fillers for elastomeric and polymer compos...

Electrorheological elastomers (EREs) have viscoelastic properties controllable by external electric fields. For their application, it is necessary to investigate the rheological properties of EREs under various loading conditions. In this work, anisotropic EREs based on a silicone rubber with 10 wt% of PI-Na polyimide particles oriented in an elect...

This paper will focus on rheological induced effect of FeCo/C-N nanocomposite particles in polyalphaolefin (PAO) as liquid medium for potential application in magnetorheological system. FeCo/C-N nanoparticles synthesized by frontal polymerization followed by thermolysis were characterized by x-ray diffraction (XRD) and transmission electron microsc...

In this paper, we derived closed form analytical solutions for the effective viscosity of the suspensions of solid spheres that take into account size effects. This result was obtained by using the solution for the effective shear modulus of particulate composites developed in the framework of the strain gradient elasticity theory. Assuming the inc...

Electrorheological suspensions (ERS) of polyimide particles with organoelement fragments from the sodium salt of 2,5-diaminobenzene sulfonic acid were obtained for the first time. Their rheological and electrorheological characteristics, their dependence on the parameters of deformation, and the intensity of the external electric field were studied...

Suspensions of polyimide particles were obtained, in which 2,5-diaminobenzenesulfonic acid was used as a diamine component. Their electrorheological properties in a nonconducting medium were studied depending on the parameters of deformation and the intensity of the external electric field. It is established that the electro-rheological suspensions...

На основе микроразмерного немодифицированного оксида титана и полидиметилсилоксанового каучука были изготовлены вулканизаты холодного отверждения. Из этих вулканизатов были изготовлены сшитые эластомерные композиты с изотропно и анизотропно распределённым наполнителем. В данных композитах был рассмотрен эффект изменения упругих свойств в приложенно...

The method of obtaining high-strength elastomeric composites based on the matrix of a copolymer of styrene butadiene (E-SBR, 30% styrene), filled with particles of rice husk ash as a reinforcing filler, is proposed. During the conducted investigations, it was established that the most efficient method of regulating the strength properties of the co...

The results of a comprehensive study of the new composites filled with modified micro and nanoscale shungit are presented. Correlation characteristics of the surface structure of elastomers and their physical - mechanical properties are deduced.
Article
At present, elastomer composites are one of the most prospective construction materials. Recently, when designing and manufacturing elastomer composite materials, constructions, and goods, much atention is paid to the problems of ecology and economic and energy efficiency. In this connection, application of mineral fillers in elastomer composite co...

Analytical modeling of mechanical behavior of elastomeric composite samples, filled with mineral ultradisperse particles of shungite, is performed in uniaxial tension. The composite matrix is assumed to be hyperelastic, while the polymer composites are elastic or absolutely stiff. The possibility of using different models in order to specify consti...

Nanoparticles are widely used as polymer composite-reinforcing additives—fillers. Understanding the interaction mechanisms and regularities responsible for nanoparticle aggregation is of great significance for elucidating the nature of reinforcing of polymer composites. The paper reports on quantum mechanics calculations and full-scale experimental...

Rheological properties of the non-Newtonian fluids in nonstationary cyclic loading are investigated. A kinematic flow model is suggested on the basis of a differential equation with coefficients that are identified by flow curves for the limit cycles. Energy dissipation of the obvious hysteresis type is considered. Approximations are built using mu...
