- The physical properties, including modulus of rupture, structural modulus and thermal expansion coefficient of segmented, large frontal area, ceramic wall-flow diesel filters are presented. The effect of cement composition, its coverage and segmentation pattern on these properties and on the failure modes during strength testing is discussed. Using these properties the mechanical and thermal integrities of LFA filter are computed and compared with those of monolithic filter,. The paper discusses both the high efficiency (EX-47, 100/17) and low efficiency (EX-66, 100/25) filter compositions.
