Abstract : This paper presents acoustic emission (AE) technique for detecting onset damage of composite materials damage
and validate this technique using actual AE data from fatigue crack growth. AE piezoelectric transducer was attached to glass
fibre reinforced polyester composite specimen during the fatigue cyclic test. For data collection, AE parameters, i.e.,
duration, amplitude, and energy near fracture zone were obtained and were correlated to fatigue life. AE signals were
obtained at four different applied loads (60.97MPa, 67.75MPa, 74.52MPa, and 81.30 MPa) which were 45% to 60% of
ultimate tensile strength (UTS) of material. The results show correlation between AE parameters and the number of cycles to
failure. This correlations show that AE can be used to predict the fatigue life and can be tool for detecting damages in
composite materials.
