Report on the mixed mode interface cohesive laws using a new test method

A new microscale testing method based on single fibres being peeled of a matrix surface in scanning electron microscope will be developed. Various peeling angles will be tested and details of the displacement field of the fracture process zone where the fibre detaches will be documented and used for the determination of a microscale mixed mode cohesive law. The delivery will be a report describing the test specimen design, manufacturing testing fixtures, testing procedures and results for 1-2 different fibre/matrix interface treatments.
