聚酰胺66的传统振动焊接工艺仅在准稳定阶段具有连续和稳定的熔体流动。已对工艺和由此产生的焊缝进行了彻底的研究。用电子束对聚酰胺66进行辐射交联会改变材料的特性。因此，在振动焊接期间产生的能量平衡改变，并且挤压流被阻碍。此外，这会导致交联在微晶熔化温度以上获得残余刚度，从而影响振动焊接工艺的特性。此外，可以观察到更高的焊接温度和熔化行为的变化。这导致了振动焊接交联聚酰胺的工艺、结构和性能之间的各种关系。因此，焊接强度可以达到基材强度的值。本文的范围是研究辐射交联对材料特性的影响，以及由此产生的加工和焊接特性。通过量热、化学、流变、力学和光学研究，强调辐射交联对聚酰胺66振动焊接工艺的影响。Polym.工程索引，55：2493-2499，2015.© 2015塑料工程师学会
The conventional vibration welding process of polyamide 66 only has a continuous and steady melt flow during the quasi‐steady phase. The process and resulting welds have been thoroughly investigated. Radiation cross‐linking of polyamide 66 with electron beams alters the material's characteristics. Consequently, the resulting energy balance during vibration welding changes and the squeeze flow is impeded. Additionally, this causes the cross‐linking to attain a residual stiffness above the crystallite melting temperature, thereby influencing the characteristics of the vibration welding process. Further, higher weld temperatures and a change in meltdown behavior can be observed. This leads to a varied relationship amongst the process, structure, and properties for vibration welding cross‐linked polyamide. Hence, weld strengths up to the value of the base material strength are possible. The scope of this article is to investigate the influence of radiation cross‐linking on the material characteristics and, by extension, the resulting processing and welding characteristics. Calorimetric, chemical, rheological, mechanical, and optical investigations serve to highlight the influence of radiation cross‐linking on the vibration welding process of polyamide 66. POLYM. ENG.
