A型蜂窝夹层结构平板基本力学性能

摘要

The basic mechanical properties of A honeycomb sandwich constructions plan were studied in this paper,NH-1-2.75-72 Nomex used as sandwich material,SW-110A/5258 glass fabric reinforced epoxy prepreg cured at 180℃ were selected for skin and adhesive film.By applying one step autocalve cure cycle,A honeycomb sandwich constructions were produced.Flexural properties,edgewise compressive propertie,flatwise compression properties,plan tension shear properties were tested.The basic mechanical properties of A honeycomb sandwich constructions plan meet the design requirement of high temperature airborne radome,satellite radome.%研究了以NH-1-2.75-72 Nomex蜂窝为芯层、SW-110A/5258高温固化环氧树脂玻璃布预浸料为蒙皮材料的A型蜂窝夹层结构平板基本力学性能.A型蜂窝夹层结构平板采用热压罐一次固化成型.测试了A型蜂窝夹层结构平板的弯曲、侧压、拉剪及滚筒剥离性能.结果表明:A型蜂窝夹层结构平板基本力学性能满足耐高温机载天线罩和卫星整流罩的设计要求.
