TESTING OF SIC TITANIUM COMPOSITES BY FRAGMENTATION AND PUSH-OUT TESTS - COMPARISON AND DISCUSSION OF TEST DATA

Interfacial properties of SiC/titanium alloy composites have been determined by two methods, namely multiple-fibre fracture (fragmentation) and push-out tests. Although the methods cannot give similar results since they are based on various modes of interface analysis, a prediction of the transfer shear stress measured in the fragmentation test has been obtained by using a simulation of the fracture process where the push-out strength is introduced as an input value along with other fibre and matrix characteristics.
