Luminous Fibers as Design Elements in Plastics Parts

The combination of light diffusing fibers and plastics or fiber-reinforced composites opens up a future-oriented topic in the field of the functionalization of lightweight materials. Especially designers be allowed to look foward: From now on, filigree contours can be realized and uniform lighting effects on the surface of lightweight components can be archieved

Leuchtfasern als Designelement im Kunststoffbauteil

Die Kombination von Leuchtfasern und Kunststoffen bzw. Faser-Kunststoff-Verbunden eröffnet ein in die Zukunft gerichtetes Feld im Bereich der Funktionalisierung von Leichtbauwerkstoffen. Was vor allem Designer freuen dürfe: Fortan können bis dato nicht umsetzbare filigrane Konturlinien und gleichmäßige Leuchteffekte auf Bauteilen erzeugt werden

Active flow control in wind turbines - integration technologies and assessment of economic effects

Synthetic Jet Actuators (SJAs), as subgroup of active flow control devices are used to influence aerodynamic parameters by introducing energy into the airflow (e.g. by suction and blowing). For the core material of fiber-reinforced wind turbines, several designs of SJA and integration concepts are developed. In regard to the thin-walled structure of the wind turbines, a flat design of the actuators was developed so that they can be embedded into the sandwich material. In order to become widely accepted, those fluidic actuators have to be technologically as well as economically advantageous. Therefore, a method has been conceptualized that allows to compare the additional costs arising from actuator integration with the additional revenues considering the entire life cycle
