Carbon black particles are fabricated from coconut shells by pyrolysis process at 400°C carbonization temperature and used as reinforcement in epoxy composites. The biocomposites were characterized for mechanical and morphological properties. Results showed that due to increases in carbonization temperature the carbon percentage increases in carbon black particles. Tensile strength, tensile modulus, flexural and flexural modulus tests were performed at different filler loading. The results indicated that mechanical properties increase as the carbonization temperature increases and also as filler loading increased when compared with the neat epoxy. From proximate analysis it is clearly observed that carbon percentage increases due to pyrolytic decomposition of raw shell particles and a good interfacial bonding was observed between filler and polymer from morphological analysis.
