Abstract
The aim of this work is to characterize the influence of power ultrasonic in combination with closed injection pultrusion to increase the impregnation quality. For this purpose, two examination methods are used. On the one hand the influence of power ultrasonic on the resin system is investigated in the laboratory. The amplitude, the sonication time and the pressure are varied as manipulated variables. On the other hand the power ultrasonic is integrated into an injection and impregnation chamber upstream of a pultrusion die. This allows the power ultrasonic to be examined under process conditions. The position and the amplitude are varied as manipulated variables. The results provide important data to understand the influence of power ultrasonic to closed injection pultrusion.
