“…Previously, shrinking tubes were inserted into the inlets and outlets to ensure connectivity to the peripheral equipment, e.g., syringe pumps for supplying reactants. PVDF was selected as manufacturing material as a result of its chemical resistance towards a broad range of chemicals [23]. In addition, the optical transparency of the polymer facilitated the observability of processes within the reactor and its thermostability reached 150°C.…”

Dedicated to Professor Rüdiger Lange on the occasion of his 65th birthdayA flexible reactor and measurement setup to safely obtain thermokinetic data for exothermic chemical reactions in plate-type microreactors is presented. Precise heat flux measurement is realized by means of Seebeck elements and allows for direct as well as space-and time-resolved heat flux determination across the reactor. The microreactor used in this work is manufactured from poly(vinylidene fluoride) foils and consists of 11 SZ-shaped mixing channel elements. The Seebeck elements are calibrated by the Joule effect, while its performance is demonstrated in heat transfer and neutralization reaction experiments. Furthermore, the local resolution enables an estimation of mixing time scale for rapid reactions. A comparison of obtained results indicates good accordance with literature data and is the base of further investigations using the calorimeter.

In the automotive industry, the increasing environmental awareness is reflected through consistent lightweight construction. Especially, the use of carbon fiber reinforced thermoplastic plays an increasingly important role. Accordingly, to the material substitution, the demand for adequate joining technologies is growing. Therefore, laser transmission welding using filler material provides a way to combine two opaque joining partners by using the process specific advantages of the laser transmission welding process. After introducing the new joining technology and the applied experimental setup, this paper will investigate the process itself and the conditions for a stable process. Fundamental studies of the absorption characteristics of the applied carbon reinforced thermoplastic and the heat distribution within the surface due to laser impact are performed. To analyze the resulting weld seam quality and to investigate the influence on the process parameters and the welding process itself, lap shear tests are carried out. After all, a thermal model for the joining process is generated and presented in this paper.

ZusammenfassungIn diesem Beitrag werden verschiedene Aspekte der ultraschallbasierten Messtechnik hinsichtlich der Materialparameterbestimmung an viskoelastischen Materialien behandelt. Zunächst wird ein viskoelastisches Materialmodell unter Berücksichtigung von Anisotropie und Kausalität erarbeitet. Nachfolgend werden zwei verschiedene Verfahren zur Charakterisierung von Materialparametern anhand von geführten Ultraschallwellen in zylindrischen und plattenförmigen Strukturen vorgestellt sowie Vor- und Nachteile diskutiert. Dabei wird ebenso auf die Betrachtung von Materialalterung eingegangen. Beispielhaft untersucht werden thermoplastische Materialien wie Polypropylen und Polyamid 6. Zur Charakterisierung starker Anisotropie wird auch auf glasfaserverstärkte Plattenstrukturen mit thermoplastischer Matrix eingegangen.
