Abstract

Composite materials are materials that are widely developed and their use has been widespread in various industrial and household sectors. Epoxy composites filled with coconut shell charcoal powder have been tested for their thermal conductivity properties using the one-dimensional conduction method. The tested specimens had dimensions of 50 mm x 50 mm x 5 mm made of epoxy and coconut shell powder with a percentage of charcoal weight of 0%, 10%, 20% and 30%. The specimen is inserted into a thermal conductivity measuring instrument made of solid aluminum which is insulated around it. The heater is mounted on the aluminum as a heat source, while the other end is left open to the free air in the room. The results showed that the highest average thermal conductivity was a 30% variation of 0.5003 W/m°C, then a 20% variation of 0.3738 W/m°C, a 10% variation of 0.3487 W/m°C. and the lowest at 0% variation without using coconut shell charcoal powder at 0.1364 W/m°C.

Abstract

Experiments to know themal conductivities of silicone rubber composite were conducted. The sillicon rubber was mixed with coconut shells charcoal powder with weight variations. The weight presentage variations were 0, 10, 20 and 30%. Increasing the weight persentage was expected to increase the thermal conductivity of the composite. The speciment size was 50 mm x 50 mm x 5 mm. The speciments were tested according to the conduction heat transfer mode. To make sure that the temperatures were steady, the experiments were performed for about 6 hours. The results indicated that increasing the weight presentage raised the composite thermalconductivities. At 0% of wight, the composite had a thermalconductivity of 0.157 W/m°C, at 10%, 20% and 30% of weight compositions; the composite had thermal conductivities of 0.461 W/m°C, 0.58 W/m°C, and 0.73 W/m°C respectively.
