Abstract
This review presents the multi-fibre fragmentation technique
(MFFT) and Laser Raman Spectroscopy (LRS) which are used for fibre-matrix
interface testing. The limitations of MFFT are summarised and ideas for
improvement are proposed.
The key findings of this review are: 1) MFFT equipment and protocols vary
considerable and require standardisation. 2) Existing models for stress
transfer between fibres rely on geometrical models that do not capture
the material properties or the constitutive models of the transmitting
matrix. Comprehensive constitutive matrix stress transfer models are
needed.
3.) Current MFFT models do not incorporate terms for matrix vibration as
a function of fibre fracture shock. It is clear that more work can also
be done to characterize microcomposite systems in compression, at various
angles to the fibre axis, and under various combinations of cyclic
loading, but arguably such work should be pursued after the uniaxial
tensile fibre fragmentation problem has been better understood.
