Abstract

Abstract Translated from German Zur Verbesserung der Durchschlagsfestigkeit von Kunststoffmassen besteht der Füllstoff aus ultrahochorientierten Polymerfasern, die vorzugsweise in der Polymermatrix des Kunststoffes in der Richtung ausgerichtet sind, in der die Wärmeableitung erfolgen soll. Es werden Wärmeleitfähigkeitswerte im Bereich von 10W/m.K bei 60% Faseranteil erreicht. Die Kunststoffmassen werden verwendet zur Wärmeableitung bei gleichzeitiger elektrischer Isolation von elektrischen und elektronischen Bauelementen und Geräten. To improve the dielectric strength of plastic materials, the filler consists of ultra-high-orientation polymer fibers, which are preferably oriented in the polymer matrix of the plastic in the direction in which the heat dissipation is to take place. Thermal conductivity values in the range of 10W / mK with 60% fiber content are achieved. The plastic masses are used for heat dissipation with simultaneous electrical insulation of electrical and electronic components and devices.
