摘要:通过采用将间位芳纶纸直接浸渍酚醛树脂模拟蜂窝格壁的方式,来研究不同密度间位芳纶纸蜂窝异面压缩强度的影响因素。观察三种不同密度的间位芳纶纸蜂窝的微观压缩破坏形貌,并对比间位芳纶纸蜂窝异面压缩强度实测值与三种计算模型计算值,从而确定该规格下间位芳纶纸蜂窝受压破坏模式。根据蜂窝材料异面压缩强度理论计算公式进行验证,间位芳纶纸蜂窝异面压缩强度实测值与塑性坍塌计算模型所得理论值对应性较好。对于孔格边长一定的蜂窝,格壁材料本身的屈服应力和厚度是影响蜂窝异面压缩强度的关键因素,而蜂窝格壁材料的厚度和拉伸弹性模量随着上胶量的增加而增加。 
Abstract:The influence factors of different densities of meta-aramid paper honeycomb on the compressive strength were studied by directly impregnating the meta-aramid paper with phenolic resin to simulate the honeycomb cell wall. By observing the micro compression failure morphology of three different densities of meta-aramid paper honeycomb, and comparing the measured value of different surface compression strength of meta-aramid paper honeycomb with the calculated value of three calculation models, the compression failure mode of meta-aramid paper honeycomb under this specification was determined. According to the calculation formula of honeycomb material's different surface compressive strength, the measured value of meta-aramid paper honeycomb's different surface compressive strength is in good agreement with the theoretical value of plastic collapse calculation model. For the honeycomb with a certain length of cell side, the yield stress and thickness of the cell wall material itself are the key factors affecting the compressive strength of the honeycomb, while the thickness and Young's modulus of the cell wall material increase with the increase of the amount of glue.
