Abstract - The experiments of this research were designed to lend itself to two way and three way classification ANOVA analysis in the SPSS software. The new hybrid epoxy matrix composites consist of 5wt 10wt 15wt 20wt 25wt and 30wt of fillers alumina and calcium silicate in nanoscale. Tensile strength of each constituent material was obtained through tensile experiments. Creep experiments were performed at temperatures of 500C 700C 900C 1100C and 1300C at constant loading of 14 MPa. The composite material with 15wt constituent showed highest tensile strength followed by the 20wt constituent showing higher strength than a baseline Epoxy-Alumina nanocomposite. Also the 15wt and the 20wt constituents exhibited the best resistant property to creep than every other constituent at short term creep tests and at analytical results. Though the two way classification ANOVA show enough significance at 95 confidence interval the three way classification ANOVA showed significances of time temperature and samples with interactions which are responsible for the creep failure of the studied composites. The creep limit property of the new material was found to be higher than the creep limit of the Epoxy filled with Alumina only.
