AE法を用いた二粒子径粒子含有GFRP中の粒子/樹脂界面の破壊メカニズムの定量化

抄録

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. There is one way to accomplish this matter is to use two diameter particles (2DP). GFRP that has the two diameter particles added (2DPGFRP) for the compatibility of the suppression of increased viscosity and the grant of non-flammability was noticed in this study. The unique fracture mechanism was shown the 2DPGFRP. That mechanism was 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 the several parameter of AE measurement.
