TENSILE BEHAVIOUR OF OPEN CELL CERAMIC FOAMS

L. Řehořek, I. Dlouhý, Z. Chlup

Tensile test methodology for ceramics foam has been developed and first findings are described. The tested material was the commercially available alumina based ceramic foam. Two cell sizes were included into the study, namely 10 and 60 PPI. The test procedure critically depends on the fixation of the ceramic foam into aluminium pots by a suitable adhesive. Two specimen geometries with cross-section 10×10 and 15×15 mm were tested and results statistically analysed. Fractographic observations enabled to explain specimen behaviour during tensile loading.
