| Abstract: | Carbon fiber(CF) was treated in oxidized air condition and all specimens of CF reinforced polyamide 1010(PA1010) composites were prepared by a micro injection machine. Experimental results show that the treated CF can considerably improve the tensile strength and tribological properties of the filled PA1010 composites. The friction coefficient of treated CF filled in PA1010 composites were decreased by 30%~50% and the wear resistance were increased by 2~3 times comparing to that of untreated CF filled in PA1010 composites. The morphology of tensile fracture and wear surface of PA1010 composites were observed and analyzed by means of scanning electron microscopy. It was found that the treated CF could effectively promote the adhesive strength between CF and pure PA1010. Moreover, the effect of mechanisms of the surface treatment of CF on the properties of the filled PA1010 composites were discussed. |
