摘要: |
本文设计了一套蜂窝芯材料在真空环境下的透气速率检测装置,用于模拟星体在发射过程中,蜂窝芯腔体内空气逸散情况。采用压差法测试了不同真空度下蜂窝芯的透气速率,同时制备了有色气体使得整个实验过程可视化,可以判断出蜂窝芯板的透气死点。实验结果为蜂窝芯材料的工程应用提供了一定的数据支持。 |

Abstract: |
In this paper, through the design of the permeability detection device of the honeycomb core material, using the pressure difference method to test the air permeability rate under different initial vacuum degrees. At the same time, the colored gas was prepared to visualize the entire experiment process, and could be used to detect the air permeable dead point of the honeycomb core board. The experimental results of the paper provide data support for the engineering application of honeycomb core materials. |
