Fiber-reinforced thermoplastics are mainly manufactured by injection molding and extrusion, whereby the extrusion compounding process is primarily used to produce fiber-filled granulates. Reproducible production of high-quality components requires a granulate in which the fiber length is even and high. However, the extrusion process leads to the fact that fiber breakages can occur during processing. To enable a significant quality enhancement, experimentally validated modeling is required. In this study, short glass fiber reinforced thermoplastics (polypropylene) were produced on two different twin-screw extruders. Therefore, the machine-specific process behavior is of major interest regarding its influence. First, the fiber length change after processing was determined by experimental investigations and then simulated with the SIGMA simulation software. By comparing the simulation and experimental tests, important insights could be gained and the effects on fiber lengths could be determined in advance. The resulting fiber lengths and distributions were different, not only for different screw configurations (SC), but also for the same screw configurations on different twin-screw extruders. This may have been due to manufacturer-specific tolerances. article_number: '3113' author: - first_name: Annette full_name: Rüppel, Annette last_name: Rüppel - first_name: Susanne full_name: Wolff, Susanne last_name: Wolff - first_name: Jan Philipp full_name: Oldemeier, Jan Philipp id: '56781' last_name: Oldemeier - first_name: Volker full_name: Schöppner, Volker id: '20530' last_name: Schöppner - first_name: Hans-Peter full_name: Heim, Hans-Peter last_name: Heim citation: ama: Rüppel A, Wolff S, Oldemeier JP, Schöppner V, Heim H-P.

In addition to established processes such as hot plate welding, infrared welding, or vibration welding, hot gas butt welding is becoming more and more important industrially due to its advantages. The main benefits are the contactless heating process, the suitability for glass fiber reinforced, and high-temperature plastics as well as complex component geometries. However, various degradation phenomena can occur during the heating process used for economic reasons, due to the presence of oxygen in the air and to the high gas temperatures. In addition, the current patent situation suggests that welding with an oxidizing gas is not permissible depending on the material. On the other hand, however, there is experience from extrusion welding, with which long-term resistant weld seams can be produced using air. Investigations have shown that the same weld seam properties can be achieved with polypropylene using either air or nitrogen as the process gas. Experimental investigations have now been carried out on the suitability of different gases with regard to the weld seam quality when welding polyamides, which are generally regarded as more prone to oxidation. The results show that weld strengths are higher when nitrogen is used as process gas. However, equal weld strengths can be achieved with air and nitrogen when the material contains heat stabilizers. author: - first_name: Max full_name: Bialaschik, Max id: '32297' last_name: Bialaschik - first_name: Volker full_name: Schöppner, Volker id: '20530' last_name: Schöppner - first_name: Mirko full_name: Albrecht, Mirko last_name: Albrecht - first_name: Michael full_name: Gehde, Michael last_name: Gehde citation: ama: Bialaschik M, Schöppner V, Albrecht M, Gehde M.
