NBR/PVC blends provide resistance to fuel and stand out with their use in fuel systems due to these properties. It is important to determine the resistance of these materials to fuel. For this reason, in this study, NBR/PVC blend was immersed in three different fuels (diesel, JP-8, Reference Fuel B) at 23°C for 72 h and subjected to tests to determine the changes in various mechanical properties. According to the test results, the NBR/PVC blend performed better in diesel and JP-8 jet fuel, with the most destructive results in Reference Fuel B. In fact, no significant change was observed in the volume of NBR/PVC after exposure to JP-8 and diesel, and it was found to decrease by 1.6% and 3%, respectively. Similar results were observed in the hardness and tensile tests, and values close to the original NBR/PVC samples results were determined after JP-8 and diesel exposures. In contrast, 10% decrease in hardness value and 24.3% decrease in tensile strength was detected in NBR/PVC samples after exposure to Reference Fuel B, as a result of significant volume increase of 14.9%. When all the results were evaluated, it was concluded that the NBR/PVC blend was more sensitive to Reference Fuel B.
