蜂窝结构板后埋件拉脱力的影响因素

Influencing Factor of Pulling Test of Post-Inserts in Honeycomb Panel

文摘介绍了蜂窝结构板上M5后埋直通连接件的拉脱力测试条件及结果,分析了后埋件胶接施工过程、胶接固化规范对后埋件拉脱力和胶接质量的影响。结果表明,沿开孔轴向竖直灌胶后再安装埋件,胶液填充效果最好,气孔最少,有利于提高拉脱力;对于EA934NA后埋胶,于室温≥22℃下完成固化,更有利于提高拉脱力。所得结果可为产品试验设计和拟定工艺参数提供参考。

In this work, the pulling test condition and test results of M5 post-insert through-hole connector in a honeycomb panel were discussed. The influence of post-insert connector application and curing processing protocol on the pulling strength and bonding quality were analyzed. It was found that the best way to apply the resin is to install the inserts after vertically fill the resin along the axial of the through holes. Minimum pores and improved pulling strength were achieved with this method. For EA934NA post-insert bonding agent, curing at room temperature （ 22℃ ） is preferable for better pulling strength. The conclusions of this work can be used as references for future prod- uct test design and processing configuration setup.
