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.
