The embedded single-fibre dynamic load test- a new non-destructive =nterphase
- Composites, 25(7), p.770-775, 1994 .
Embedded single-fibre tests are commonly used to investigate fibre/matrix adhesion. However, unstable crack propagation renders these destructive tests hard to interpret. Most of the relevant theories apply an energy or a strength criterion to indirectly deduce interphase properties from the obtained results. A new method, the embedded single-fibre dynamic load (SFD)test, was developed to measure interphasial viscoelastic properties directly in a non-destructive way. Using different fibres in combination with poly(phenylene sulfide)in a comparative study, it is shown that results from the SFD test correlate well with those from single-fibre pull-out (SFP)tests. The morphology is established as a key link for an understanding of the fracture behaviour as well as the dynamic-mechanical behaviour of the interphase in fibre-reinforced composites.
