Peeling and characterisation of the carbon fibre-based radicular adhesive anchorage interface

Abstract : Carbon fibre plates (20 x 5 mm) were characterised by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray-induced photoelectron spectroscopy (XPS). The 90 degrees peeling test was used (0.5 mm s(-1)) at the carbon fibre Panavia F-(R) interface. The fracture interfaces were analysed using both SEM and EDS. Panavia F-(R) was characterised from the theological point of view using a plate-plate fixture fitted on the Stress Tech((R)) Rheometer. The fracture patterns were mixed, cohesive in the adhesive or interfacial between the adhesive and the carbon fibre plates. The presence of Panavia F-(R) between the carbon fibres was demonstrated on the fracture interfaces (EDS analyses) lending weight to the theory that this adhesive was mechanically retained on composite plates. Even so, the fact that the presence of O=C bonds was shown opened up the possibility of a chemical bond between the primary and the composite material.
