This article presents the effects of nanosilica content on some properties of nanocomposite based on K-153 epoxy resin (K-153 epoxy resin was made by modifying ED-20 epoxy resin with thiokol and oligomer acrylate, simultaneously) and polyethy​lene polyamine (PEPA) (as a hardener). Results show that nanosilica of lower than 1.5 weight percent (wt%) was suitable for K-153 epoxy resin in manufacturing polymer composite. At 80 oC, gelation of K-153 epoxy resin with 1.5 wt% was 79,15 % in comparison to 75,28 % of K-153 neat epoxy. Tensile strength and flexural strength of nanocomposite with 1.2 wt% of nanosilica were 79.81 MPa and 98,14 MPa higher than those of K-153 respectively (53.30 MPa and 60.81 MPa). Besides that, thermal oxidation resistance and remaining ash of nanocomposite also increased in comparison to K-153 epoxy resin.
