ASTM C1674-11<\/h3>\n

Historical Standard: Standard Test Method for Flexural Strength of Advanced Ceramics with Engineered Porosity (Honeycomb Cellular Channels) at Ambient Temperatures<\/h4>\n
\n

ASTM C1674<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of the flexural strength (modulus of rupture in bending) at ambient conditions of advanced ceramic structures with 2-dimensional honeycomb channel architectures.<\/p>\n

1.2 The test method is focused on engineered ceramic components with longitudinal hollow channels, commonly called \u201c<\/span>honeycomb\u201d<\/span> channels. (See Fig. 1.) The components generally have 30 % or more porosity and the cross-sectional dimensions of the honeycomb channels are on the order of 1 millimeter or greater. Ceramics with these honeycomb structures are used in a wide range of applications (catalytic conversion supports (1)<\/span>, high temperature filters (2, 3)<\/span>, combustion burner plates (4)<\/span>, energy absorption and damping (5)<\/span>, etc.). The honeycomb ceramics can be made in a range of ceramic compositionsalumina, cordierite, zirconia, spinel, mullite, silicon carbide, silicon nitride, graphite, and carbon. The components are produced in a variety of geometries (blocks, plates, cylinders, rods, rings).<\/p>\n

1.3 The test method describes two test specimen geometries for determining the flexural strength (modulus of rupture) for a porous honeycomb ceramic test specimen (see Fig. 2):<\/p>\n

1.3.1 Test Method A<\/span>\u2014<\/span>A 4-point or 3-point bending test with user-defined specimen geometries, and<\/p>\n

1.3.2 Test Method B<\/span>\u2014<\/span>A 4-point- \u00bc<\/span> point bending test with a defined rectangular specimen geometry (13 mm \u00d7<\/span> 25 mm \u00d7<\/span> > 116 mm) and a 90 mm outer support span geometry suitable for cordierite and silicon carbide honeycombs with small cell sizes.<\/p>\n

1.4 The test specimens are stressed to failure and the breaking force value, specimen and cell dimensions, and loading geometry data are used to calculate a nominal beam strength, a wall fracture strength, and a honeycomb structure strength.<\/p>\n

1.5 Test results are used for material and structural development, product characterization, design data, quality control, and engineering\/production specifications.<\/p>\n

1.6 The test method is meant for ceramic materials that are linear-elastic to failure in tension. The test method is not applicable to polymer or metallic porous structures that fail in an elastomeric or an elastic-ductile manner.<\/p>\n
