| Abstract: | The effects of surface treatment and additional content of glass-fiber on mechanicalproperties of fiber reinforced MC nylon composite (GFRMCN) are studied. The GF/MCNYLON interface and its effect on the properties of GFRMCN are also analysed by usingSEM. The results show that KH550 as coupling agent is efficeint to the GFRMCN; the tensile strength, tensile modulus, fie-cure strength, fie-cure modulus and impact toughness ofGFRMCN composite(40wt% of G. F. ) are respectively increased by 32. 2%, 152%, 74. 3%,117% and 162%,compared with MC nylon. According to the characteristics of material processing, 30% ~ 40% additional content of glass-fiber is suitable, which guarantees materialhaving comprehensive mechanical properties and good processing property. |
