Processing Controlled Properties of Thermoplastic-based Nanocomposites
The composition of nanocomposites has an impact on their processing options. In return, the position and orientation of fillers and the quality of the particle/matrix interphase as well as the structure formation in the polymer matrix depend on the processing histories. How-ever, there are almost no investigations on such topic.
The contribution of this work focuses on the influence of the extreme high level of strain and shear processes on the morphology (orientation and crystallization) and mechanical behaviors of thermoplastic-based nanocomposites with different filler loadings in order to investigate whether or not the high mechanical performances of nanocomposites could be exploited in the welds. Therefore the welds made of Nano-SiO2 and nano-TiO2 reinforced polypropylene (PP) as well carbonnanotubes-filled (CNT) polyoxymethylene (POM) were systematically studied. They were compounded using a two-screw extruder and followed by injection molding. The related plaques were joined by linear vibration welding. The influence of the processing parameters and filler content on the morphology and finally on the weld quality were completely investigated through light microscopy, scanning electron microscopy und mechanical testing.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
