By a News Reporter-Staff News Editor at Clinical Trials Week -- A new study on Clinical Research is now available. According to news reporting originating from Terni, Italy, by NewsRx correspondents, research stated, "EPDM/aramid ablatives represent the state of the art heat shielding materials for Solid Rocket Motors. Due to their mechanical properties and excellent thermal stability, aramid fibers or pulp constitute the common reinforcement of EPDM based liners."
Our news editors obtained a quote from the research from the University of Perugia, "New generation organic fibers were recently tested as a potential replacement of aramid. In this study, Kynol fiber, a phenolic based reinforcement with high mechanical and thermal properties, was evaluated on this class of ablatives: to date, there are no data available on the use of Kynol fibers in EPDM based ablatives. At the same time, silica fibers which are traditionally used on other classes of ablatives, were also tested: in fact, the use of this type of reinforcement is not well documented on EPDM ablatives. It was found that EPDM/Kynol composition produced the char with the smaller dimensional change and the higher adhesion on the virgin material. EPDM/aramid exhibited the higher insulation properties. At the studied fiber percentage, EPDM/silica showed the worst behavior than the other formulations."
According to the news editors, the research concluded: "The obtained data improved the comprehension of the role of the different fibers on the ablation mechanism of this class of ablatives, thus enabling the possibility to exploit their intrinsic properties."
