Based on the AE source simulation method proposed in the first report, we studied the dynamics of microfractures in unidirectional GFRPs with different interfacial qualities. Three types of microfractures were revealed by the AE source simulation. AE event counts due to the Mode-I fiber fracture, Mode I and II interfacial fractures(debonding and disbonding)were observed at higher stresses in UD-GFRP with poor interfacial qualities(with wax in matrix)than in UD-GFRP with good interface quality, but increased rapidly with an increase of stresses. Dynamics of microfractures changed depending on the interfacial qualities.
