Hermetic sealing in bridge engineering and culvert waterproofingPolymer 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.
Methodological Approaches to the Improvement of Technology of Engineering FluorocompositesPolymer 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 matrixPolymer 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 MaterialsPolymer 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
Adhesive-Material Combustibility-Reduction Methods. Part 1Polymer Science, Series D - Tập 16 - Trang 268-272 - 2023
A. P. Petrova, A. Yu. Isaev, A. S. Emelyanova, L. I. Bocharov
Combustibility requirements for aircraft materials are shown. Data are presented about the main methods of making adhesives less combustible by adding fire retardants, such as halogenous and phosphoric compounds, as well as mineral fillers that release carbon dioxide and water vapor upon heating. Properties and purposes of low-combustibility adhesives, as well as adhesive-combustibility testing me...... hiện toàn bộ
High-Temperature Thermodestruction Analysis of a Polyphenylene-Sulfide-Based Composite by ThermogravimetryPolymer 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
