Abstract
Methods and apparatus for testing the strength of ceramic honeycomb structures are described. The apparatus includes a chamber that utilizes a flexible, generally cylindrical member including integral flanges to apply compressive force to the periphery of the honeycomb structure. According to some embodiments, a portable apparatus with an open chamber is provided to allow for rapid testing of multiple honeycomb structures.
Claims9
An apparatus for testing the compressive strength of a ceramic honeycomb samples comprising:
- a main housing including a generally cylindrical chamber and a generally cylindrical, flexible member disposed within the main housing, the flexible member defining a sample loading and testing area and a gap between the flexible member and the main housing, the gap providing a fluid holding area;
- a top plug and a bottom plug for sealing the chamber;
- a hydraulic pressure generator for supplying fluid under pressure to the fluid holding area and to expand the flexible member to provide uniform pressure on the periphery of the sample;
- and
- means for automatically moving samples in and out the sample loading and testing area, wherein the means for automatically moving samples in at out the sample loading and testing area includes a retractable plunger.
