Foreword

GB/T 34520 "continuous silicon carbide fiber test method" is divided into seven parts. --- Part 1. Beam wire sizing rate; --- Part 2. Single fiber diameter; --- Part 3. Line density and density; --- Part 4. Beam tensile properties; --- Part 5. Tensile properties of single fibers; --- Part 6. Resistivity; --- Part 7. High temperature strength retention. This section GB/T 34520 Part 4. This section drafted in accordance with GB/T 1.1-2009 given rules. This part is proposed by China Aerospace Science and Technology Corporation. This part of the National Aerospace Technology and Application Standardization Technical Committee (SAC/TC425) centralized. This part of the drafting unit. National University of Defense Technology. The main drafters of this section. Wang Jun, Wang Hao, Jane Branch, Wang Yifei, Song Yongcai, Wang Yingde, Shao Changwei, Gou Yan Zi, Wang Xiaowu, Wang Bing, Tang 祚 Jiao.

4 test principle

The tensile strength and tensile modulus of the continuous SiC fiber bundle are determined by stretching the fiber bundle after the impregnated resin is cured Damage to determine. The tensile strength is obtained from the breaking load divided by the cross-sectional area of the continuous SiC fiber bundle, and the tensile modulus of elasticity is the amount of change in stress And the corresponding strain change ratio. Elongation at break is the ratio of the elongation at elongation to the gauge length at beam load loading up to the maximum load.

5 test environment

5.1 Standard test conditions According to the provisions of GB/T 1446, the temperature of 23 ℃ ± 2 ℃, relative humidity of 50% ± 10%. 5.2 In other environmental conditions for testing, the test environment temperature and relative humidity should be specified in the test report.

6 test equipment and materials

6.1 test machine Testing machine should meet the provisions of GB/T 1446. It is recommended to use a constant speed tensile testing machine with a pneumatic clamp, the range of not less than ......
