Fibre Matrix

An energy balance approach is proposed for the single fibre composite (or fragmentation) test, by which the degree of fibre-matrix bonding is quantified by means of the interfacial energy, rather than the interfacial shear strength, as a function of the fibre geometrical and mechanical characteristics, the stress transfer length, and the debonding length. The validity of the approach is discussed using E-glass fibres embedded in epoxy, both in the dry state and in the presence of hot distilled water.

A novel technique was recently introduced in our laboratories for the measurement of the compressive strength of single fibres, based on a modified configuration of the single fibre composite fragmentation test. In particular, the effect of the length of the embedded fibre on its compressive strength was assessed for the first time, based on Weibull statistics considerations. Moreover, during the sample manufacturing stage, a fibre can break in compression due to induced cooling stresses, rather than mechanical stresses, which can be determined from the fragmentation phenomenon. In this note, improved analyses of such compressive fragmentation effects are presented and discussed.
