Durability Study on Si-SiC Material for DPF (3) 2005-01-0582
The durability of a silicon carbide diesel particulate filter (SiC-DPF) is important because SiC-DPF are often utilized under severe operating conditions. This paper presents test results under long-term operation. The static, cyclic and dynamic fatigue properties of silicon-bonded SiC (Si-SiC) materials were investigated. Creep strain was not observed at normal operation temperature (600°C). Samples did not fracture in cyclic fatigue tests after more than 105 cycles at both 9MPa at 600°C and 2MPa at 1000°C. Furthermore, from dynamic fatigue testing, it is predicted that there would be no deterioration in strength in at 600°C, as well as at room temperature (RT) with respect to time.
