| Abstract: | By using test instrument, such as material testers, impact testers, braking dy- namic test stands, the mechanical properties and friction performance of composite brake shoes manufactured both at home and abroad are comprehensively inspected and analyzed. Experimental results indicate that overseas brake shoes have higher impact strength, lower compressive strength, compression modulus and wear rate compared with the home - made brake shoes, and consequently they have better operating performance and longer service lives. |

| Keywords: | composite brake shoe mechanical property tribological performance wear rate |
