IMPROVED CRASH-RESISTANT FUEL CELL MATERIAL
Abstract
Basic physical tests pertaining to Specifications MIL-T-6396 and T-27422 were performed on materials coded ARM-018 and ARM-021. These tests were conducted first on the ARM-018 to substantiate and document the improved performance shown by this material in earlier laboratory tests and actual aircraft crashes. Material failure mechanics under a variety of static and dynamic loading conditions were included to accurately simulate and measure crash performance. As the test series progressed, some deficiencies were discovered in the ARM-018 material. These included low dynamic puncture and tear resistance. A careful analysis of the problem area led to changes in material processing, and the resultant composition was given the code name ARM-021. Although the basic ingredients remained the same, this modification of material showed great superiority over the ARM-018 in both puncture and tear resistance. Because of the considerable improvement of the ARM-021 material over conventional crash-resistant materials and because of deficiencies in test standards of crash resistance found in MIL-T-27422, changes in this specification have been suggested.
