摘　　要：研究了不同封边工艺制作的芳纶蜂窝夹芯板材的耐环境性能,包括耐湿热性能、浸水实验及耐盐雾老化性能。实验结果表明:湿热环境对夹层复合材料的平拉强度、剥离强度会造成不同程度的负面影响,而盐雾环境的影响相对较小。通过比较,在力学性能方面,树脂封边工艺具有更好的耐湿热性能,将此工艺应用于产品可以提升芳纶蜂窝夹芯复合材料的耐环境性能。The environmental performance of aramid fiber honeycomb sandwich panel made by different edge sealing technologies was studied,including moisture and heat resistance,water immersion test and salt spray aging resistance.The experimental results show that the tensile strength and peel strength of the sandwich composites are negatively affected by the wet and hot environment to varying degrees,while the influence of the salt spray environment is relatively small.By comparison,in terms of mechanical properties,the resin edge sealing process has better moisture and heat resistance,and the application of this process to products can improve the environmental resistance of aramid honeycomb sandwich composites.
