Mechanical Behaviors Study of Epoxy Resins Reinforced with Nano-SiO2 Particles

Abstract

Abstract. Epoxy resin composites filled with nanoparticles are widely used for electrical devices such as insulators, VLSI package and rocket engine shell materials. An experimental study on the mechanical property of SiO 2 -filled epoxy resin composite was carried out by the electronic universal testing machine. The prepared experimental specimens were made of three nano-SiO 2 particles(15nm, 30nm and 50nm) at different weight fractions (2%, 4% and 8%). Mechanical characteristics including yield strength limit, elastic modulus were obtained. The experimental results showed the addition of nanoparticles will improve the mechanical performance of the epoxy resin composite. Its improvement was better for yield limit with the nanoparticles content of 2% , and for yield limit and elastic modulus with the nanoparticles radius of 30nm.
