Verification and Assessment on the Aviation Pouring Organic Glass's Comprehensive Performance under Different Environment Conditions

摘要

The performance variations of pouring organic glass under the different accelerated aging test conditions whose brand is YB- 3 have been studied, which have reached the specified life, the result show that the overall trends the properties of the YB- 3 being used the specified life slightly decrease following the experiment time increasing, which include tensile property, bending property, stress-solvent (95% ethyl alcohol). When the samples have been respectively experienced 360h damp heat test, 720h heat aging test, 720h salt fog test, bending strength are respectively 143.2MPa, 130.5MPa, 141.6MPa and the bending strength retention rate are higher 90 percent, tensile strength are respectively 68.1MPa, 69.7MPa, 68.3MPa and the bending strength retention rate are higher 92 percent, stress-solvent silver grain (95% enthyl alcohol) are respectively 18.8MPa, 20.8MPa, 16.9MPa., which are no less than this type material's indicator. Although the YB-3 has reached the specified life, the performance only slightly decline and has the potential to continue to use a certain calendar time.
