When compared with the traditional materials, the advantages of composite materials are high strength, stiffness, lightweight, heat resistance, moisture resistance, chemical and corrosion resistance to aggressive environments, low thermal conductivity, and design flexibility.
The problem of monitoring the condition of composite material has become relevant to the development and widely used of composite materials.

Fig. 2a shows the morphology of materials at 80/20 of H2 and C2H4 content.
High quality materials are defined by the high inflection temperature, as well as the small differences existed between the on-set and end temperatures, owing to the presence of highly graphitized structures [15].
