Abstract

Carbon ceramic composites of local materials from coconut coir waste with clay matrix or organoclay have been successfully fabricated. The composites have successfully demonstrated the thermal and electrical conductive properties. The research variables are composition ratio of 1: 10, 2: 10, and 3: 10% weight, and sintering temperature of 800 o C, 900 o C and 1000 o C. The higher the content of the coconut coir powder the higher the electrical conductivity the composite produces. Likewise, the higher the composite sintering temperature, the higher the electrical conductivity of the composite. The electrical conductivity value of the optimal carbon ceramic composite is produced by composites with a composition ratio of 1:30, at a sintering temperature of 900 o C. The higher the carbon contents, the lower the thermal conductivity of composite. Increased pyrolysis sintering temperatures do not increase the thermal conductivity of composites. The optimum value of thermal conductivity is generated by carbon ceramic composites at a pyrolytic sintering temperature of 900 o C, at a ratio of 1: 10. In general, increasing sintering temperature does not change the composite density. Composite density tends to be constant to increase sintering temperature. Increasing the content of coconut coir powder, which turns into carbon, is shown to decrease composite density.
