The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00004 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

Краткое описание

Calculation of the effective activation energy of thermo-oxidative breakdown (E) of modified epoxy composite materials is carried out on the basis of thermogravimetric analysis using the Broido double logarithmic method. The maximum values of activation energy (E = 152.1 kJ/mol and 152.3 kJ/mol) were found experimentally for composite materials modified by 0.25 wt.% and 0.50 wt.% of 4-aminobenzoic acid, respectively. The values obtained indicate a significant effect of modifier on the activation energy of epoxy composite materials. The results found experimentally show the formation of relatively thermally stable intra- and intermolecular bonds, which indicates the improvement of cross-linking of epoxy composite macromolecules. Improving the cross-linking of epoxy composite macromolecules leads to an increase of thermal stability, which as a result, has an effect on increasing the materials durability.
