Abstract

The main purpose for this project is to investigate the effect of nano calcium carbonate on the mechanical properties of epoxy composite reinforced recycle rubber. Different weight percentage of nano calcium carbonate will give different mechanical properties to the epoxy composite. The reinforcement of elastomers by particulate fillers is achieved largely on the basis of physical interactions between the filler and the rubber matrix. In recent years, nano-size organic particles have attracted considerable attention as new toughening agents, because the resulting materials exhibit uniquely high thermal and mechanical properties. Nano-CaCO3 powder is the cheapest commercially available, and has the additional advantages of a low aspect ratio and a large surface area. This project is start from preparing of sample by adding the epoxy resin with recycle rubber with ratio 1 : 0.4. The material were stir using mechanical stirrer at speed 500rpm until it mixed. After that nano CaCo3 powder will added with 5 different weight percent (0%, 2%, 4%, 6%, and 8%). The nano-CaCO3 powder was added and mixed using the mechanical stirrer mill at speed 500 rpm for another 5 min. Then the epoxy hardener were added in the same manner, at speed 500 rpm for 5 min. After the mixture is prepared, this mixture will poured into the mould and then wait about 5 hour until it cured. Then the sample will cured inside the furnace and be heated at 140 °C for 1 hour . After curing, mechanical tests were performed and the fractured surfaces of the specimens were examined under Scanning Electron Microscopy (SEM). The results show that as we increased the nano CaCo3 to the epoxy composite, the strength of mechanical properties are been improved.
