In literature, composite is defined as composition of two or more constituent materials which in turn results
a material having greater properties as compares to base materials. FBG sensors started to be used in
composite materials with the developing technology because of it’s unique properties which allows ones to
monitor the inner events among the layers of the composite material. So that FBG sensors can be easily
embedded into composite materials such as Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber
Reinforced Polymer (GFRP). When FBG sensors embedded into the composite laminated, ones will be
eligible to observe temporary and permanent changes as well as deformations within the composite material.
Especially in avionic and space applications, embeding FBGs into composite materials allows ones to have
a proper structral health monitoring and testing system. Eventually, using FBG sensors in such fields allows
to monitor the material integrity, deformation, health status and by that unnecessary maintenance, waste of
time and money will be prevented. Use of avionic application areas.
