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: 0.7 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: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RÉSUMÉ

The objective of this paper is to present a new binder system that can be applied in composite rocket propellants to improve the properties of these propellants, not only for better performance but also to reduce waste and pollution. This novel system is based on the oxygenated thermoplastic elastomer (TPE) binder, which consists of a multi-block segmented polyether-b-block amide (PEBA) copolymer (alternating hard and soft segments) with the addition of a plasticizer, wetting agent, and an anti-oxidant. A series of tests were conducted to determine the properties of solid rocket propellants based on this binder system. The effect of the novel TPE binder system on the burning rate and mechanical properties of ammonium perchlorate (AP)-based propellants is demonstrated. Also, the thermal behavior of these propellant compositions was studied. The results show that propellants based on the novel TPE binder have a better energy performance than today's workhorse hydroxyl-terminated polybutadine/AP propellant, possess appropriate mechanical properties, and exhibit good processing and aging characteristics at low cost.
