Objective To study the effect of nano-SiO 2-x on the mechanical properties of high strength glass fiber reinforced EAM resin.Methods Polymerio-Nano-Fiber composites were prepared whose reinforced material were nanometer SiO 2-x and fiber S-GF and resin materials were EAM resin and BPO. The properties of prepreg and composites were studied.Results The strength and modulus of composites increased significantly by nanometer SiO 2-x. When the content of nanometer SiO 2-x was 5%, the flexural strength of composites increased by 55.6%( 1702.4Mpa).Conclusion Many properties of compsites were increased with nanometer SiO 2-x.
