| Summary: | In this study, the effect of carbon black (CB) and recycled rubber (RR) loading on properties and characterization of epoxy/recycled rubber/carbon black were studied. In the first part, the effect of different carbon black loading was investigated. The composites were prepared by using a mechanical stirrer at speed of 600rpm at room temperature. The effect of carbon black (CB) loading of epoxy/CB on density, flexural properties, fracture strength, morphological, electrical and thermal properties were
investigated. The carbon black that were used as a filler at 5, 10, 15 and 20 vol.% of loading. Density of the epoxy/CB increased as CB loading increased. Unlike density, the flexural properties, with every increase in CB loading the flexural properties show a declining trend. For fracture toughness, the result shows that, with every increase of CB filler loading, the toughness of epoxy/CB decreased. On the first part, a 15vol% of CB was able to reach the percolation. With addition of CB to epoxy composite was able to improve the thermal stabilities of epoxy/CB composite if compared to neat epoxy. Meanwhile in the second part, the 15vol.% of carbon black was used to determine the effect of different recycled rubber loading of epoxy/recycled rubber/carbon black. The same processing method was use and the effect of different loading of recycled rubber loading at 0, 2, 4, 6, 8 and 10phr was investigated on density, flexural properties, fracture toughness, morphology, electrical properties and thermal stability was investigated. With addition of 15 vol.% of CB to epoxy/RR blend, increases the density properties. |
