Tensile testing of high porous ceramic materials

In last years cellular materials are getting to focus of an interest in a number of industrial applications and science fields. These materials are often used for filtration of different mediums or in aerospace industry and even in tissue engineering. Hence, there is effort to understand and describe mechanical and physical properties of these materials. While behaviour of these materials in compression is well understand and published, tensile tests are not so frequent and concerning ceramic cellular materials they are highly rare. The methodology of evaluation of tensile properties of model ceramic open-pore foam material VUKAPOR((R))A used like filters in metallurgy was developed. This methodology is based on fixation of ceramic foam sample by specialised resin to a holder. Homogenous transfer of forces is ensured by this technique. Specimens of two sizes – 10x10x30mm and 15x15x40mm were tested. Ceramic foams with two pore densities – 10 PPI and 60 PPI have been investigated
