Composite with Aren Fiber (Waste of Starch Fiber) as an Insulator and Sound Reducer

Abstract:

In this research, waste of Aren fiber is utilized for raw material of composite. This aren fiber composite is used for insulator and sound absorber. The Aren composite is manufactured by pressing technique of mixture of aren, resin and hardener occur for 24 hours. The composites made from aren composite are tested in term of thermal conductivity and ability of sound absorber. The research aims to study an effect of resin to fiber ratio, size of Aren fiber to thermal conductivity, and sound absorber ability of aren composite material. The result shows that the optimum thermal conductivity of Aren composite is found to be 0, 3950 kcal/m h0C. This composite is obtained with resin-fiber ratio of 7:1, fiber length of 1 cm, 10% hardener, and pressure of 70 kg/mm2. Meanwhile, for optimum sound absorber composite is obtained with resin-fiber ratio of 6:1, fiber length of 2 cm, 10% hardener, and pressure of 70 kg/mm2. The composite has noice reduction of 40,1 dB and transmission loss of 46,1 at frequency of 500 Hz.
