The addition of particulate flame retardant to matrix resin is required in order to apply GFRP in the field needed the nonflammability because GFRP doesn’t have fire resistance. However, this method accompanies the increase in resin viscosity. We focused on GFRP that has the two diameter particles added (2DPGFRP) for the compatibility of the suppression of increased viscosity and the grant of non-flammability. In our past study, the 2DPGFRP was showed to have unique mechanical properties that the difference in bending strength depending on which the resin applied surface (Top side) and the mold surface (Bottom surface) is tensile side. That mechanical properties were clarified qualitatively using the AE method etc. in that study. However, the detailed consideration about parameters except the AE count has not been concluded in our past study. The consideration about these parameters is expected to be clarified quantitatively the detailed fracture behavior. In this research, the fracture mechanism on 2DPGFRP was clarified by detailed AE measurement.
