In the present work it is suggested that the degree of fibre—matrix bonding can be quantified by means of an energy for the nucleation of an interfacial debond, rather than by using a stress-based interfacial parameter The energy necessary to initiate/nucleate an interfacial crack from its associated transverse fibre break during a single-fibre fragmentation test is calculated. The interface energy for the initiation of debonding is shown to be a function of the fibre and matrix geometrical and material characteristics, and of the initia debonding length. The novelty of the present work lies in the in-depth examination of the relative roles of the physical parameters that appear in the proposed theoretical mode
