Mechanical Property of Nano-Particles Reinforced Epoxy Resin Composite Materials

Abstract

The two kinds of composites, including nano-nitrile butadiene rubber (NBR)/epoxy resin (EP) and nano-acrylate/EP composites were prepared with the three-roll mill. The effect of nano-particles on the mechanical property of epoxy resin composites were investigated by tensile strength testing. SEM images were taken to characterize the decentralization of the nano-particles in the composites. Mechanical testing results were presented that the epoxy nano-composites has the higher tensile strengths after filling with nano-particles. The tensile strength of EP composites has been significantly improved with nano-NBR content 4 wt. % and the nano-acrylate content 3 wt. %, respectively. SEM results indicated that nano-particles can be evenly dispersed in the epoxy resin by the three-roll mill dispersion method.

Using Recycled Rubber Particles as Filler of Polymers

“…Increasing concentration of recycled rubber leads to proportionally decrease values of hardness, tensile strength and shear strength. This conclusion confirms the hypothesis based on works of authors [1,7,9,10,11,12,15,18,19], that the inclusion of inorganic particles with this dimensions and this mechanical and physical properties decreases tensile and shear strength. The presence of air bubbles leads to the initiation of cracks, which is consistent with the assumptions of the authors [2,13,14].…”

Thermoset Composite on Basis of Recycled Rubber

“…Cerbu and Curtu [7] mention using the recycled rubber together with glass fibres at epoxy resins -the presence of recycled rubber particles led to increasing the impact strength. Lv et al [8] made experiments with nano-composites nano-butadien-rubber (NBR)/(EP) and with nano-acrylate/EP composites. The presence of rubbers nano-particles led to increasing the tensile strength.…”
