摘要

Abstract

The effects of superfine titania fibers on the properties of friction

wear rate

heat-resistance and crystallinity of polyether ether ketone (PEEK)were studied.For comparison

the properties of PEEK filled with nano-TiO2 were also studied

and related mechanisms were discussed.Compared with nano- TiO2

superfine titania fibers showed higher abilities in decreasing friction coefficient and improving wear resistance and heat-resistance of PEEK owing to its micro-reinforcing and wear resistance ability.Whether under lower loads or higher loads

superfine titania fibers reinforced PEEK composites showed lower friction coefficient and wear rate than those of nano-TiO2/PEEK composites.Moreover

the worn surfaces and transfer films of titania fibers reinforced PEEK composites were more smooth and flat.Under 200 N

the wear resistances of 5%—10% titania fibers reinforced PEEK composites were 3.28—7.63 times higher than that of PEEK composites filled with the same content of nano-TiO2.
