Özet:

This study is aimed to produce polymer composite material with low thermal conductivity coefficient and high mechanical strength. Therefore, different rates of boric acid and paper mill sludge were added to the polyester matrix and the composite materials are characterized in terms of mechanical and thermal properties. Based on the experimental results, the addition of paper mill sludge and boric acid improved the bending strength and partially thermal resistance of the composite material and led to decrease in the decomposition temperature values. It was determined that paper mill sludge and boric acid decreased the thermal conductivity coefficient. The experimental results demonstrate that the utilization of boric acid and paper mill sludge in polyester based composite material production improves the mechanical and thermal properties of the material.
