For the real time characterization of pultrusion processes with a complex temperature control, two finite-element modeling approaches utilizing a continuous model with lumped material properties for a cured composite have been developed. The first procedure, based on the mixed time integration scheme and the nodal control volumes method, is working in the ANSYS Mechanical environment, but the second procedure is performed using the ANSYS CFX software with the cure reaction introduced as an additional variable. New cure sensors measuring the temperature and electrical resistivity of resins have been developed for the inline process control. To demonstrate the accuracy and reliability of the numerical procedures and new sensors, two technological processes with a temperature control examining the pultrusion of I-beam and rod profiles have successfully been analyzed.

通过温度控制实时表征拉挤成型工艺

为了实时表征具有复杂温度控制的拉挤成型工艺，已经开发了两种有限元建模方法，它们利用具有固化复合材料集总材料特性的连续模型。第一个程序基于混合时间积分方案和节点控制体积法，在 ANSYS Mechanical 环境中工作，但第二个程序使用 ANSYS CFX 软件执行，固化反应作为附加变量引入。已开发出用于在线过程控制的新型固化传感器，可测量树脂的温度和电阻率。为了证明数值程序和新传感器的准确性和可靠性，
