Full understanding of response of highly porous (cellular) ceramic foams to different mechanical loadingconditions is important because of their potential use in industry, medical and other applications. A new technique for testing tensile strength of ceramic foam materials has been developed and first knowledge is described in the paper. Testing procedure consists of fixation of ceramic foam into aluminium pots by suitable adhesive. Alumina based ceramic foam material produced by Lanik (CZ) was used for the test methodology development. Samples were produced by polyurethane foam replication technique. Foams having 10 and 60 pores per linear inch (PPI) were tested. Basic fractographic analysis was carried out by scanning electron microscopy (SEM) to get corresponding figure about specimen behaviour during tensile loading. Influence of increasing PPI (decreasing cell size) on tensile strength of specimens was experimentally proven. With increasing PPI the tensile strength decreases. Slight dependence of tensile strength on sample size of examined material was observed in the range of the tested specimen dimensions. PDLLA-coated samples were alsoproduced and tested, exhibiting nearly 10 times higher tensile strength.
