Abstract:

Temperature and strain are two of the most significant parameters in the curing process of composites. The fabrication of the strain-free temperature sensor has been completed by encapsulating fiber Bragg grating (FBG) with capillary ceramic tube. The grating string composed of a bare grating and an encapsulated grating has been embedded in the composites. The temperature and strain of the out of autoclave curing process have been monitored. In addition, the accuracy of the temperature monitoring has been proved by comparing the temperature monitoring results with common gratings, high temperature-resistant gratings and thermocouples, respectively. It is found that the high temperature-resistant gratings are more suitable for composites curing process, especially for the monitoring of out of autoclave curing process at the internal high temperature. This study provides a reference for multi-parameter monitoring by using gratings in out of autoclave curing process of composites.
