Test show that wear loss of developed friction disk is less, anti - abrasion properties and employment lifespan is superior to that of asbestos friction disk either in normal or sliding case.
The friction and wear tests of the self lubricating bearing made of carbon fiber reinforced copper matrix composite materials are arranged by uniform design that can greatly reduce the test duration.
