中文摘要：

针对液态浸渗挤压复合材料成形过程实施难度大、工艺参数和成形过程难以控制的现存问题，以PCI数据采集控制卡为核心，采用LabVIEW软件设计开发了工艺实时监控系统；实现了对工艺过程中重要参数的在线采集、显示与存储，利用该监控系统进行液固挤压复合材料实验，基本实现了对温度等关键工艺参数的过程控制；实验结果表明了该系统的可靠性，从而为真空吸渗挤压复合材料工艺的实际应用奠定了基础。

英文摘要：

A real--time monitoring system is developed, which is aiming at the difficulties of controlling liquid--solid extrusion process and the key parameters. Based on this system, the key parameters can be on--line collected, displayed and saved simultaneously. In addition, with this system the processing parameters can be controlled. Finally, the results from the acquisition proved that the system provides a feasible way to monitor the process and has established a foundation for practical application.
