An effect of the plastic deformation on the interfacial energy of a fiber-reinforced polymer matrix composite is studied to evaluate the initiation of the interfacial debonding. We performed the fragmentation test with a model glass fiber-reinforced vinylester matrix composite, and calculated the interfacial energy with the energy balance method taking into account an energy dissipation of the plastic deformation. The following results are confirmed; the plastic deformation has a significant influence on the interfacial energy, and the energy balance scheme considering the plastic energy dissipation leads to the constant interfacial energy without reference to the amount of the released potential energy. The differences between our model and the previous one are discussed.
