ABSTRACT Self‐lubricating microcapsules containing methyl silicone oil as core materials, were prepared with poly(melamine‐formaldehyde) shell material by in situ polymerization method. Combining synergistic effect of the short carbon fibers (SCFs) which systematically treated liquid‐phase oxidation and chemical grafting, they simultaneously adopted reinforcing additives to improve tribological mechanical properties polyurethane materials. The behaviors composites have been investigated a block‐on‐ring wear tester electronic universal testing machine, respectively. results indicate that friction coefficient rate without SCFs significantly decreased increased self‐lubricating microcapsule concentration from 2.5 10 wt % due release oil; meanwhile, filled 15 not only exhibited lowest behaviors, but also improved strength thermal stability composites. © 2017 Wiley Periodicals, Inc.
