摘要:从SiCp/Al复合材料性能分析着手,讨论了预置件法、焊接法和粘接法等在空间遥感器研制中常用的联接方法的优缺点,提出了在高体积分数(体分)SiCp/Al复合材料上直接加工螺纹,并加装钢丝螺套的方法来改善螺纹联接性能。对在某高体分SiCp/Al复合材料上加工的M4、M5螺纹进行了拉伸测试,结果表明:加装钢丝螺套前,复合材料螺纹有被拉脱现象;加装钢丝螺套后,M4螺纹、螺杆在3 000~4 000 N被拉断;M5螺纹、螺杆在8 000~9 000 N被拉断,测试后两种规格的螺纹状态良好,可以满足实际应用对该材料拉伸强度的要求,其已应用于工程项目中。

Abstract:Based on analysis of properties of SiCp/Al composites, the advantages and disadvantages of common connecting methods for space optical sensors such as fore-imbedding, welding and bonding were demonstrated. A new method of machining threads directly on high volume fraction SiCp/Al composites and mounting steel wire thread sleeves to improve the thread connection was proposed. The tensile test for M4 and M5 threads on high volume fraction SiCp/Al composites were performed. Obtained results suggest that some of them are pulled out before mounting the steel wire thread sleeve. However, M4 and M5 screws are pulled off under 3 000-4 000 N and 8 000-9 000 N, respectively, after mounting the steel wire thread sleeve. The M4 and M5 threads show good shapes, which means that machining threads directly on high volume fraction SiCp/Al composites and mounting the steel wire can meet the requirements of the engineering for tensile strength and it is already used in some projects. -
