Plasma Technology for Deposition and Surface Modification
Plasma processing is a high-technology discipline in tailoring surface properties and in obtaining functional polymers of advanced materials without changing the material's bulk. Comparing with solid polymeric materials, special care should be taken for surface activation of textiles due to their complex geometries. It was found that modification is strongly influenced by both plasma parameters and fabric structure. As compared to air, CO2, and water vapor, Ar/O2 and He/O2 mixtures were found to be very effective for surface hydrophilization of polyester textiles due to the long-lasting free radical lifetimes. The modified surfaces were not stable for a long time due to restructuring of the ...
Textile Dyeing
The coloration of fibers and fabrics through dyeing is an integral part of textile manufacturing. This book discusses in detail several emerging topics on textile dyeing. "Textile Dyeing" will serve as an excellent addition to the libraries of both the novice and expert.

Entwicklung eines Verfahrens zur Weiterverwertung von Produktionsverschnitt aus unausgehärtetem Epoxidharz-Prepreg
Wie können Produktionsabfälle einer industriellen Faserverbundfertigung recycelt werden? Seit den frühen achtziger Jahren werden kohlenstofffaserverstärkte Kunststoffe (CFK) in der Luftfahrtindustrie in großem Umfang eingesetzt. Erst jüngere Entwicklungen richteten den Fokus auch auf das Ende des Produktlebenszyklus, das Recycling dieser Werkstoffe. Zwar können CFK-Werkstoffe bereits heute mittels Thermolyse recycelt werden, dabei geht jedoch die Hälfte des Werkstoffes – der Polymeranteil – verloren. Die Arbeit widmet sich der Frage, wie CFK-Produktionsreste verlustfrei direkt weiterverwertet werden können und stellt technisch validierte Lösungen zur Verarbeitung sowie ein Modell zur analytischen Abschätzung der mechanischen Eigenschaften solcher Mehrphasenverbunde dar.

A rapid virtual autoclave for carbon fiber reinforced plastics
Structural carbon fiber reinforced plastic parts are usually manufactured through autoclave processing for high-performance aerospace applications. Today’s aerospace composite manufacturing techniques require high quality with robust manufacturing processes. Manufacturing process simulation enables the investigations of physical effects and manufacturing process mechanisms. This approach has been increasingly used to predict and optimize the manufacturing process for high part quality at low manufacturing costs. Owing to a complicated manufacturing environment involving multi-physics characteristics, there is a critical need to develop an efficient and cost-effective numerical methodology ...
