| Abstract: | In nano-composites,the nano-sized particles can enhance some performance of the matrix.In order to study the composites’ mechanical properties at varying strain rates and to investigate the modification effects of nano-particles,the dynamic mechanic experiments on nano-SiO2/Nylon 6 composites are carried out by means of split Hopkinson tensile bar.In addition,the influences of strain rate and nano-particles on the properties of matrix are discussed.In the end,the enhancing mechanism of nano-materrials is analyzed.The results show that nano-SiO2 has reinforced the mechanical properties of Nylon 6 matrix. |
