Specimen for testing on FIMATEST
Fibre-reinforced composites use a matrix to distribute loads evenly across all fibres. The matrix also provides high interfacial shear strength, which is crucial for effective load transfer. Traditionally, researchers used macromechanical tests to measure this strength. However, these tests suffer from variability caused by fibre content, diameter, orientation, and operator handling during specimen preparation.
The recent release of ISO 19375 “Fibre-reinforced composites — Measurement of interfacial shear strength by means of a micromechanical single-fibre pullout test” overcomes these limitations by enabling precise measurement of pure fibre-to-matrix adhesion.
FIMATEST, comprising the FIMABOND embedding station and the FAVIMAT + single fibre tensile tester, is the first commercial system worldwide to measure fibre-to-matrix adhesion per ISO 19375 standard. This robust testing solution is ideal for manufacturers of reinforcement fibres, sizings, and matrices, as well as for research institutions.
