| 摘要： | A detailed test method comparison was performed to assess the equivalence of test methods for composite materials, with emphasis on the Committee for European Standardization and ASTM International test methods referred to in the SAE International Aerospace Material Specification (AMS) 2980 and 3970 specifications. This comparison included both the parameters associated with two comparable test methods and the additions and changes listed in the AMS specifications. For the types of tests where only one test method is referred to in the SAE specifications, a second comparable ASTM or Suppliers of Advanced Composite Materials Association test method was selected for comparison purposes. In total, two test methods were reviewed and compared for a total of 16 different types of tests. For each type of test, three comparison tables are presented, focusing on geometric features of the specimen and test fixture, parameters associated with the test procedure, and procedures for data reduction and reporting. Each table contains a list of individual parameters specified in the test methods as well as any additions or changes provided in the AMS 2980 and 3970 specifications. For every parameter listed in the comparison tables, an assessment of the equivalence was made using a 0-4 rating scale. A brief summary of each test method comparison is provided, which emphasizes the most significant differences between the test methods. |
