摘要: 超长可卷绕收展薄壁大变形复合材料杆由于轻质、高收纳比功能,作为百米级大型空间展开结构的主支撑部件。开展了超长复合材料薄壁豆荚杆的连续固化成型技术研究,设计了半豆荚杆连续固化和全豆荚杆连续胶接成型的过程及设备。建立了成型过程过渡区的有限元分析模型,分析了豆荚杆展开-收拢过渡区长度对应力水平的影响,确定了成型过程过渡区的最小长度。依据连续固化过程的压力及脉动时间参数,对豆荚杆的固化成型设备进行了调试运行。通过17 m超长豆荚杆样件的试制,验证了成型设备及过程的设计合理性。

Abstract: Ultra-long Thin-walled deployable composite boom with high strain ability are of considerable interest used in the main support component of hundred-meter-size deployable spacecraft structures due to their light weight and high folding-storage ratio function. This research seeks to investigate continuous curing technology of an ultra-long thin-walled deployable composite boom made of high strain carbon-fibre-reinforced-plastics. The equipment and process for continuous curing of semi-thin-walled boom and continuous adhesion of thin-walled boom are designed. The effect of the length of the translational traction zone from unfolding to reeling on the stress level during continuous forming process is simulated by finite element model for determining the minimum length of the transition zone of the equipment. The test run of the continuous molding equipment for thin-walled boom is conducted according to the formulated pressure and pulsation time parameters in the curing process. The design rationality of the moulding equipment and process is verified by the trial-manufacture of 17 m ultra-long thin-walled deployable boom sample.

Key words: ultra-long thin-walled deployable boom, continuous curing, continuous adhesion, moulding process
