Sound insulation performance of short cotton fibre waste/recycled acrylonitrile butadiene styrene composites

Abstract

Recyclability is one of the key subjects in the automotive industry to reduce environmental pollution and economic aspects. Today, in an average passenger car, around 150–200 kg of polymer materials are used. One of the most used plastics in the vehicles is acrylonitrile butadiene styrene (ABS) polymer. In the presented study, a recycled ABS based sound insulation composite materials were developed by reinforcing with cotton fiber wastes. Recycled ABS (ABSr) is dissolved at room temperature with chemical solvents and mixed with different weight percentage (10%, 20%, 30%) cotton fiber wastes. The mechanical properties, the sound insulation coefficient, and sound transmission coefficients of the developed materials were obtained. The developed materials were concluded according to cotton fiber waste weight percentages.
