Expanded measurement uncertainty concept for the calibration of Charpy pendulum impact machines Erweitertes Messunsicherheitskonzept bei der Kalibrierung von Charpy‐Pendelschlagwerken

open access: yesMaterialwissenschaft und Werkstofftechnik, EarlyView.
When calibrating a pendulum impact machine, a large number of parameters must be determined. It is shown how the resulting measurement uncertainties can be calculated and, using an example, it is presented which components are of great relevance, which can be neglected and which have so far mostly been disregarded.

Influence of additive manufacturing and injection molding on chemical alterations of thermoplastic polyurethanes: analysis of isocyanates and oligomers Einfluss von additiver Fertigung und Spritzguss auf chemische Veränderungen von thermoplastischen Polyurethanen: Analyse von Isocyanaten und Oligomeren

open access: yesMaterialwissenschaft und Werkstofftechnik, EarlyView.
This study explores the chemical changes in thermoplastic polyurethanes (TPUs) during injection molding and additive manufacturing processes. Using diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) and gas chromatography/mass spectrometry (GC/MS), the formation of isocyanates and extraction of oligomers are analyzed.
