Abstract
In the Waterworks Bureau, the activated carbon was used for filtering the water. After use the activated carbon, they were disposed. In this work, we tried to make that composite to recycle these carbons. These wasted activated carbons were used for the filler of composite materials, and we got the composite with the carbon contents of 10%〜60%. To evaluate of mechanical behavior of these composites, tensile test and stress relaxation test were carried out. The results show the powder contents dependency on tensile strength and Young's modulus. As seen in the results of stress relaxation test, the effect of powder contents on stress relaxation was revealed. To evaluate the electric property, the electric resistance was measured by 4-terminal method during tensile test and stress relaxation test. By the measurement of electric resistance, these composites can be used as smart materials.
