Rheological and Functional Properties of PA12/W Shielding Composites with Different Density

Yang Jun,Huang Xinying,Li Yunbo,Chang Zhen,Hou Zhanjie,Tang Xing,Zhu Yubin(School of Materials Science and Engineering,Shanghai University,Shanghai 200072,China)  
Through changing content of tungsten(W),Nylon(PA) 12/W shielding composites with different density were prepared by means of melt blending and injection molding.The rheological,impact and shielding properties of the composites were characterized with melt flow indexer,impact testing machine and computed tomographic scanner.The results show that when the density is below 11.0?g/cm3,the flow behaviors of the composites accord with pseudoplastic flow behavior,and the shear rate has minimum effect on the melt viscosity of the composite with the density being 11.0g/cm3 and it is most suitable for injection molding.With the density increasing,impact strength of the composites decreases,CT value and attenuation rate to X-ray increase.When the density is 11.0 g/cm3,the impact strength of the composite is 24 kJ/m2,the CT value reaches about 17 500 and is close to the value of plumbum,the attenuation rate to X-ray is 97%.According to the comprehensive properties,the composite with the density being 11.0 g/cm3 can be used for producing X-ray shielding parts.
