Abstract
The reinforced polymer composites service life depends on long term aggressive environments. Among the ageing environment mechanism an important one is the combination of moderate high temperature and moisture. Long Period Grating Fiber Sensors (LPGFS) can be used as sensors embedded into composite material polymer matrix for measuring the moderate high temperature and moisture. There are presented the simulation results of a such LPGFS optical sensor.
