M5复合材料螺栓的设计与试验

为解决机械连接过程中金属紧固件与复合材料结构热膨胀不匹配问题,开展了复合材料螺纹紧固件研制。通过分析比较,选择了合适的树脂体系,并对成型工艺方法进行了研究,研制了M5复合材料螺纹紧固件。同时创建了数值仿真分析模型,对紧固件力学性能进行了预示。试验结果表明:复合材料紧固件性能满足设计要求,并成功研制出了复合材料螺纹紧固件,扩大了树脂基复合材料结构的应用范围。

Design and Experiment of M5 Composite Material Bolts

To solve the metal fasteners and composite materials for thermal expansion mismatch mechanical connection process, this paper carried out the development of composite materials threaded fasteners. Through analysis and comparison, appropriate resin system was choosen, and molding methods were studied.We developed a M5 composite threaded fasteners and created a numerical simulation model.The mechanical properties of the fastener simulation was expended, test results show that the composite fastener material properties meet the design requirements. Composite threaded fasteners were succefully and the applications range of resin matrix composite structures was further expanded.
