通过使用集成折射计和光纤布拉格光栅的独特光纤传感器，可以完全监控商业热固性树脂的固结。特别是，通过测量热化学转变引起的光学性能变化来跟踪树脂聚合反应的进展和演变。另一方面，光纤布拉格光栅已用于在线检测树脂凝胶化的开始。实验结果证明了所开发的传感器系统的能力和效率，可以提供有关热固性系统固化周期期间发生的主要现象的完整信息。 (c) 2005 Elsevier Ltd. 保留所有权利。
The consolidation of a commercial thermoset resin has been completely monitored by using a unique fiber optic sensor integrating a refractometer and a fiber Bragg grating. In particular, the advancement and the evolution of the resin polymerization reaction have been followed by measuring the optical properties changes induced by the thermo-chemical transformations. On the other hand, the fiber Bragg grating has been used to detect on-line the resin gelification onset. The experimental results demonstrated the capability and the efficiency of the developed sensor system to provide complete information on the main phenomena occurring during the cure cycle of a thermoset based system.
