中文摘要：
为研制可折叠、自动展开复合材料豆荚杆，对其设计、制备技术进行了探索，并完成了功能实验验证研究。根据豆荚杆使用条件和环境，确定了超薄复合材料结构，通过真空袋法和胶结工艺，制备了豆荚杆。采用有限元法进行了轴向压缩承载能力分析计算，验证了制件可以满足设计指标要求；完成了其在室温下的压扁、卷曲和自动恢复形状的功能实验验证；通过扫描电镜（SEM）照片和红外（IR）图谱，分析和讨论了其功能机理。研究结果表明，超薄可折叠复合材料豆荚杆满足功能要求。
英文摘要：
The paper seeks to address practical and novel techniques on fabrication and validation of collapsible and deploy- able lenticular tube, successfully completing function tests. From the practical conditions, a thin ply laminated system is de- signed. By using finite element analysis （FEA） code, numerical simulation on axial compression critical load of collapsible lenticular tube is conducted to verify design indexes. The collapsible lenticular tubes are manufactured by using the vacuum- bag molding and co-bonding process and then are employed for the flattening, curling and reconversion tests in room temper- ature to verify their functions. Finally, based on the scanning electron microscopic （SEM） photographs and Infrared （IR） spectra, the function mechanism of the tube is analyzed and discussed. It is shown that the thin ply laminate and collapsible lenticular tube meet the function requirements.
