Notes:
This paper describes a technique to fabricate instrumented composite cylinders made bythe filament winding process and based on the insertion of Bragg grating sensors contained in anoptical fiber, so that real time monitoring of the temperature and strain response can be made. Themain advantage of this method is that, for the first time, the strain response of the wound layers as afunction of time and temperature can be monitored during fabrication without alteration of thecomposite structure, since the sensor is a filament itself. The sensor data reveals the existence ofseveral phenomena related to the manufacturing process and material response. The results showthat during the curing stage of the fabrication of the composite cylinders there is a dimensionalcontraction without change in temperature which indicates that a material transformation occurs,and also that at the last stage there is a residual compressive strain which may affect the in-servicebehavior of the composite cylinder
