| Abstract: |
| Preparing one kind of epoxy resin that endure high temperature to sealing stuff, which adopts the liquid acid anhydride as the solidifying agent, adopts the graphite and hydroxyl-terminated liquid rubber as toughner. The effect of raw material and preparation technology on the abradability and mechanical properties of this stuff. The testing results showed that this kind of meritorious service capacity stuff has high strength, high toughness, good temperature shock properties, good abradability, and has been used to produce the sealing-circle in turbojet engine. But also, the manufactures technology can affect the temperature exparsion coefficient, hardness, grinding quality of that stuff. |
| Key words: turbojet engine sealing-circle abrasive and sealed |
