复合板料摆碾铆接、胶接和混合连接性能研究

CONNECTION PROPERTY OF JOINING COMPOSITE SHEETS WITH ROLLING RIVETING,BONDING AND HYBRID JOINTS

使用摆碾铆接、胶接和摆碾-胶接混合连接技术对玻璃纤维增强树脂基复合材料进行连接,通过拉伸试验检测该连接方式下的静强度。比较了不同连接方式的连接效果,分析了胶接时间、有无垫圈、多铆钉对连接强度的影响。实验表明摆碾-胶接混合连接能够有效提高连接件强度;垫圈对抗拉伸性能影响最大,加垫圈试件承载能力可显著提升29.46%;在一定时间范围内,胶接时间的延长可以大幅度提高连接件的静强度;然而与拉伸方向一致的双铆钉使用不能提升板料拉伸性能。

The connection quality of glass fiber reinforced resin matrix composites connected by rolling riveting, bonding and hybrid （rolling riveting/bonding） joints was studied by tensile tests. The effects of different connection methods on connection quality were compared. A series of tensile tests were carried out for test pieces obtained from different joint conditions, such as different bonding time, the presence or absence of washer and number of rivets. The experiment results show that the connection performance had been improved significantly by using hybrid joints of glass fiber reinforced resin matrix composites. Furthermore, the washer is the most important influencing factor on the connection property. The bearing capacity of test pieces with washers had been increased by around 29% than that of the one without washers. In addition, to some extent, the bearing capacity of test pieces could be enhanced a lot by the extended time of bonding. However, the connection property with two rivets at the same direction as ten- sile test could not be improved.
