Synthesis, mechanical and thermal properties of carbon black/epoxy composites

Tanusree Bera, S.K. Acharya, Punyapriya Mishra


In the present work, epoxy/carbon black (CB) composites were made with 1, 2, 3, 4 and 5 wt. % of CB. The tensile test, flexural test, and impact test of the epoxy/CB composites and neat epoxy were performed and, their results were compared. The
results conclude that the tensile strength, flexural strength, and impact strength of the 4 wt. % of CB composites is better than the other composites and neat epoxy. Thermal graphic analysis (TGA) and differential scanning calorimeter (DSC) of the pure epoxy and composites were calculated and analyzed. The results found that the glass transition (Tg) of the neat epoxy was increased with the addition of CB content up to 4 wt. % and then it was decreased. The decomposition temperature of the composites was increased with the increased in the CB content.

Keywords: Carbon black (CB), Epoxy, composites, TGA, DSC, Glass transition temperature (Tg)
