| 摘 要： | 利用搅拌摩擦焊实现了纤维增强树脂基复合材料的焊接,获得了焊接接头力学性能并分析了接头形成和断裂机制。结果表明,由于搅拌摩擦焊过程中搅拌针的摩擦剪切及对塑化材料的挤压作用,使树脂基体发生塑化并带动碳纤维迁移形成焊接接头,在搅拌头旋转速度950 r/min,焊接速度38 mm/min时,接头拉伸强度可以达到52.43 MPa,接近母材强度的51%,焊接接头的断裂机制主要为基体剪切断裂和纤维-基体界面脱粘。

| Abstract: | Fiber reinforced resin matrix composites were welded by friction stir welding process, and the joint formation and fracture mechanism were studied. The results show that well welded joint can be obtained when the resin is fully plasticizing migrated, which is attributed to the extrusion of friction for the friction stir needle and squeezing effect of plasticizing material;Joint strength of 52.43 MPa can be achieved, and approximately 51%of the base material, when the rotational speed is 950 r/min, welding speed is 38mm/min. The micro-fracture mechanism of the joint is the matrix shear fracture and interfacial debonding of fibre and the matrix. |
