In contrast to classic engineering materials hollow sphere structures show special properties regarding vibroacoustic behaviour. Due to their macro- and microscopic structure these materials seem to provide properties engineers require, but previously could not be achieved with standard materials. In this chapter the vibroacoustic behaviour is discussed in detail. The chapter is roughly split into...
Im Rahmen einer Qualitätsprüfung wurden Schäden an für den Hochbau vorgesehenen Hülsen entdeckt. Die angerissenen Hülsen wurden fraktographisch und metallographisch untersucht. Die Bruchflächenbelegung konnte mittels energiedispersiver Röntgenanalytik (EDX) als Zink detektiert werden. Am Schliffbild unter dem Rasterelektronenmikroskop (REM) wurden zahlreiche Nebenrisse festgestellt, die komplett mit...
This article describes a new development made by CREAVAC. It includes a new evaporating system for metallization of polymers with layers over 10 μm. The Company CREAVAC has developed the technology as well as the tools to produce such layers in an effective way. Providing the means for a stress-free coating process, together with the ability to use different metals simultaneously or one by one without...
