Simulation of Optimal 3D Printing Parameters
Polymer Science, Series D - - 2023
I. S. Nefelov, N. I. Baurova
Hermetic sealing in bridge engineering and culvert waterproofing
Polymer Science, Series D - Tập 4 - Trang 53-57 - 2011
O. A. Lukinsky
The problems connected with the reliability of waterproofing and hermetic sealing of the expansion dams and couplings of separate units in bridge constructions are considered. In the author’s opinion, the most reliable material for this purpose is mastics and self-adhesive materials of the Abris type.
The Use of Multipurpose Modifiers in Adhesive Compositions Based on Chloroprene Rubber to Increase Thermal Stability
Polymer Science, Series D - Tập 14 - Trang 38-41 - 2021
N. A. Keibal, V. F. Kablov, V. V. Ismailov, V. S. Sakhnova
Experience in the use of multipurpose modifiers in adhesion systems based on chloroprene rubber, which increase the performance characteristics of adhesive joint of vulcanized rubbers, is described. It is shown that the developed modified adhesive composition possesses high thermal stability and improved adhesion characteristics.
Methodological Approaches to the Improvement of Technology of Engineering Fluorocomposites
Polymer Science, Series D - Tập 16 - Trang 386-391 - 2023
S. V. Avdeichik, E. T. Krut’ko, A. S. Antonov, V. A. Struk, A. N. Lesun
Structural and technological aspects of obtaining composite materials based on polytetrafluoroethylene are considered. It is shown that, due to the manifestation of the inertness of the components in the processes of interfacial interaction with an increase in the degree of filling, a structural paradox appears within the framework of the traditional technological paradigm. This paradox consists i...... hiện toàn bộ
Thermal protection with a nanomodified epoxy matrix
Polymer Science, Series D - - 2013
S. A. Koitov, V. N. Mel’nikov, I. V. Beketov, A. P. Safronov
The results of investigations on the creation of a composite structured by Al2O3 nanopowder operating by the ablation principle for thermal protection of aircraft instead of TZMKT-8 or as an external layer of double-layer heat-resistant coating are presented.
Reinforcing Fillers for Polymer Composites Based on Organic Unwoven Materials
Polymer Science, Series D - Tập 12 - Trang 170-173 - 2019
A. N. Marycheva, T. A. Guzeva, P. M. P’e, L. Kh. Tun, G. V. Malysheva
The results of an experimental and theoretical evaluation of the duration of impregnation process in the manufacture of multilayer glass fiber and unwoven material composites are presented. Two types of unwoven materials differing by degree of microstructure have been selected. It has been established that the duration of the impregnation process using the vacuum infusion technology differs by mor...... hiện toàn bộ
High-Temperature Thermodestruction Analysis of a Polyphenylene-Sulfide-Based Composite by Thermogravimetry
Polymer Science, Series D - Tập 16 - Trang 137-141 - 2023
A. V. Kutsenova, E. V. Kalugina, A. V. Samoryadov, V. B. Ivanov
Thermodestruction of a polyphenylene-sulfide-based composite at temperatures up to 800°C was studied by dynamic thermogravimetric analysis. Activation energies Еа were determined using a nonlinear regression analysis within the framework of a kinetic model of the process with two noninterrelated noninteracting stages. Estimates of Еа by this and other methods were compared with the value of Еа dur...... hiện toàn bộ
Theoretical Determination of the Minimum Thickness of a Polymer Layer Providing Ensured Protection of a Shaft–Bearing Joint from Fretting Corrosion
Polymer Science, Series D - Tập 13 - Trang 45-49 - 2020
A. S. Kononenko, A. A. Solovyeva, V. F. Komogortsev
Fretting corrosion in a shaft–bearing joint has been investigated. The effect of the elastic characteristics of the polymer material and surface roughness of the shaft and bearing on the magnitude of the minimum possible thickness of the polymer layer at which it would be assured of retaining strength characteristics has been theoretically studied. A design equation for this magnitude has been der...... hiện toàn bộ
Development and tests of thermally stable potting and impregnating compounds
Polymer Science, Series D - Tập 5 - Trang 145-149 - 2012
S. N. Gladkikh, E. N. Basharina, O. L. Troitskaya, S. P. Kriulina, N. V. Timoshchenko, I. V. Nikitushkin
The results of investigation of domestic impregnating and potting compounds that can function at temperatures up to 180–200°C developed at JSC Kompozit are presented. It is shown that these materials function at temperatures up to 200°C, as well as under conditions of elevated humidity and temperature cycling.
The Mechanism of the Initial Stage of Synthesis of Polydopamine
Polymer Science, Series D - Tập 15 - Trang 30-34 - 2022
A. V. Varankin, A. A. Artyukhov, M. I. Shtil’man, Ya. O. Mezhuev
Based on the analysis of the regularities of the interaction of dopamine borates and dimethyl silyl ether, two alternative mechanisms of their oxidation for the purpose of obtaining polydopamine as a promising product for the creation of new and efficient adhesive compounds for joining biological tissues are proposed. An explanation of the presence of a threshold concentration of dopamine in the r...... hiện toàn bộ
