Abstract

Study aims to elucidate the fracture dynamics of brittle glass fiber reinforcement in a viscoelastic matrix, typical phenomena in the loaded GFRP, by the quantitative source inversion of elastic wave or acoustic emission (AE). We developed a new AE system to measure the out-of-plane displacement of the elastic wave and a source inversion processing to the out-of-plane displacement. The proposed inversion processing, taking into account the wave attenuation and response delay of the P-wave in the polymer matrix, enables us to study the fracture dynamics of various microfractures in loaded GFRP.
