| Research Abstract |
In the present study, an integrated multi-functional fiber-optic sensor system for monitoring molding process of polymers has been developed by combining FBG strain sensors and refractive-index sensors for monitoring cure index. The system has been applied to process monitoring of FRP. From the results, it is shown that cure index and generation process of residual strain could be measured quantitatively. In addition, it appeared that the softening of resin, resin flow and initiation of voids could be observed.
