Abstract
A conventional vibration welding process of fiber-reinforced Polyamide 66 is characterized by a continuous melt flow in the quasi-steady phase. This squeeze flow leads to a disadvantageous fiber reorientation in the weld zone. The fibers are oriented parallel to the melt flow and thus perpendicular to the common stress direction. This causes relatively low weld strength compared to the strength of the base material. Radiation crosslinking fiber-reinforced Polyamide 66 with electron beams influences the material characteristics. As a consequence, the resulting energy balance during vibration welding is changed and the squeeze flow is impeded, thus averting the fiber reorientation in the weld seam. The scope of this article is to demonstrate the influence of radiation crosslinking on fiber orientation in vibration welds. Mechanical, calorimetric, rheological, scanning electron microscope, and light microscope investigations serve to highlight the influence of radiation crosslinking on the vibration welds of fiber-reinforced Polyamide 66.
