With the aim of studying the effect of glass fiber/matrix interfacial quality on the dynamics of microfractures in GFRP, we propose a new source simulation of dissipative elastic waves. We measured the out-of-plane displacements by the longitudinal wave(P-wave)using a developed AE monitoring system and computed them by the convolution integral of assumed fracture dynamics with the analytical transfer function of the medium(Green' function of the second kind), by taking into account both the orientation dependence of velocity and attenuation of the P-wave. We also propose a new computer algorithm for estimating the source locations and fracture modes by using the arrival time and radiation pattern analysis of the P-wave. The first report introduces the proposed AE source characterization algorithm and acoustic properties of an unidirectional GFRP. Macroscopic elastic properties of UD-GFRPs with different interfacial qualities prepared by adding a small amount of paraffin wax are also reported in this paper.
