Abstract:
Composite materials such as carbon fiber reinforced plastics are used in various fields.
They are used in hydrogen pressure vessels in hydrogen stations because of their light weight
and high rigidity. However, it is difficult to inspect damage inside the material, either visually
or by hammering. Acoustic emission (AE) methods that analyse the elastic waves generated by
defects inside the material can facilitate the evaluation of internal damage. However, the analysis
of the elastic waves is challenging because of the various types of fracture such as fiber fracture
and matrix crack and because of the multiple reflections between fibers. In this study, a
comparison between simulated and experimental AE signals was performed, and the signals
were classified based on their characteristics. The simulated AE waveform is a convolution of
the simulated elastic wave evaluated by the FDTD method, and the sensor response is evaluated
using the long bar method. The performance of the AE classification is validated by the similarity
in the waveform features of the experiment and simulation waves.
