本研究采用线性振动焊接技术将不同填充量的碳纳米管增强聚氧乙烯进行连接。研究了不同碳纳米管含量的振动焊接聚氧甲烷纳米复合材料的拉伸性能随填料载荷和焊接压力的变化规律。结果表明,在聚氧乙烯中加入碳纳米管可以略微提高基体的拉伸强度,但明显降低了纯聚氧乙烯的延展性。有趣的是,在2 MPa的高焊接压力下,纳米复合材料的焊接强度也高于聚合物基体的强度。在形貌分析的基础上,讨论了产生高焊接强度的可能原因。变异较大。ENG。科学。中文信息学报,56(6):636 - 642,2016。©2016美国塑料工程师学会
In this study, carbon nanotubes reinforced polyoxymethylene with different filler loadings was joined by using linear vibration welding technique. The tensile properties of vibration welded polyoxymethylene nanocomposites with different carbon nanotube contents were studied as functions of filler loading and weld pressure. The results showed that the addition of carbon nanotubes into polyoxymethylene slightly improved the matrix tensile strength and pronounced decreased the ductility of pure polyoxymethylene. Interestingly, the weld strength of the nanocomposites was also higher than the polymer matrix strength even at high weld pressure of 2 MPa. Possible reasons for this high weld strength are discussed based on the morphological investigations. POLYM. ENG. SCI., 56:636–642, 2016. © 2016 Society of Plastics Engineers
