Progress in Preparation and Application of Honeycomb Sandwich Structure

蜂窝夹层结构具有比强度、比刚度高的特性,可作为轻质高承载结构件。随着蜂窝芯和蒙皮材料的发展,为满足高轻质化、高精度、尺寸稳定性等需求,蜂窝夹层结构由金属蜂窝逐渐向复合材料蜂窝方向转变,并均已实现工程化应用。碳纤维增强树脂基蒙皮与铝蜂窝芯子的组合结构目前为国内研究热点,但在深空探测技术的不断发展下,C/C复合材料在真空环境下出色的耐高温性能使其成为深空探测领域的理想材料。本文分析了由不同材料制备的蜂窝夹层结构材料的优缺点,逐一介绍了不同蜂窝夹层结构材料的制备方法和应用,并对碳纤维复合材料蜂窝结构的工程化应用进行了展望。

Honeycomb sandwich structure has the characteristics of high specific strength and stiffness,which can be used as lightweight and high bearing structure.With the development of honeycomb core and skin materials,in order to meet the needs of high light quality,high precision and dimensional stability,the honeycomb sandwich structure has gradually changed from metal honeycomb to composite honeycomb,and all of them have been applied in engineering.At present,the composite structure of carbon fiber reinforced resin base skin and aluminum honeycomb core is a hot research topic in China.However,with the continuous development of deep space exploration technology,the excellent high temperature resistance of C/C composites in vacuum environment makes it an ideal material in the field of deep space exploration.In this paper,the advantages and disadvantages of honeycomb sandwich structure materials prepared by different materials are analyzed,the preparation methods and applications of different honeycomb sandwich structure materials are introduced one by one,and the engineering application of carbon fiber composite honeycomb structure is prospected.
