RIA: Ultrasonic Cure Monitor for Polymer-Matrix Composite Materials

这项RIA奖将开发一种固化监测技术，该技术可以集成到自动控制方案中，以实现复合材料结构的经济制造。它将基于用于层状石墨/环氧复合材料加工的超声波固化监测(UCM)技术的方法，以及将超声波速度和衰减与复合材料的固化状态相关联的必要的分析工具。在此基础上，将开发一个用于固化循环优化和控制的综合过程模型。

This RIA award will develop a cure monitor technique which can be integrated into automated control schemes for economical manufacturing of composite structures. It will be based on the methodology of the ultrasonic cure monitor (UCM) technique for use in the processing of laminated graphite/epoxy composite materials as well as the necessary analytical tools to relate ultrasonic wave speed and attenuation to the cure state of the composite. From this, a comprehensive process model will be developed for use in cure cycle optimization and control.
