Abstract: Dispersibility of the nanoparticles in the matrix is one of the critical factors influencing various properties of nanocomposites. To address the issue of agglomeration in nanocomposites and negate the effects on properties, surface treatment of nanoparticles is seen as the viable solution. This study is focused on the influence of alumina nanofiber (NafenTM) loadings and surface treatment of the alumina nanofibers (NafenTM) on thermal and mechanical properties of polyester/E-Glass composites. Loading levels of 0.25wt%, 0.5wt%,0.75wt% and 1wt% for both untreated alumina nanofibers and silane surface treated alumina nanofibers were selected and are dispersed into polyester resin using three-roll mill. Transmission Electron Microscopy (TEM) revealed that at higher loading levels, the alumina nanofibers tend to agglomerate. Thermogravimetric analysis was performed on the unreinforced nanocomposite coupons and the increase in thermal degradation behavior with addition of nanoparticles. Silane treatment of alumina nanofibers have seemed to improve the lower onset degradation temperature. Static mechanical studies were performed. The mechanical behavior improved with addition of alumina nanofibers. Major improvement in properties is observed at 0.25wt% and 1wt% silane treated alumina nanofiber modified glass polymer composites.
