Controlled Pultrusion Process including in-situ quality-control

随着复合材料应用领域的不断扩大，拉挤作为复合材料异型材的一种连续生产工艺变得越来越重要。为了在高速拉挤过程中将废品率降到最低，必须在整个过程中测量芯棒的位置和树脂的固化，并在必要时进行调节。在研究项目中，将开发一种在线传感器技术，可以对整个过程进行连续监测。因此，该工艺的生产速度可以优化，保持良好的精度和材料变化水平。

Pultrusion, as a continuous production process of composite profils becomes more important because of the growing areas of application of composite materials. To minimize the rejection rate in the pultrusion process at high process speed, both the position of the mandrel and the cure of the resin must be measured during the whole process and if necessary regulated. In the research project, an inline sensor technology which allows continuous monitoring of the whole process is going to be developed. The production speed of the process can thus be optimized maintaining an excellent precision and material variant levels.
