In Noise, Heat and Vibration Insulator from Coconut Fiber Composite??? coconut fiber and natural rubber were mixed in a cold press process in a mold to fabricate the composite. It was with a different composition of natural rubber from 0 percent to 60 percent respectively. A mold of ten millimetres in thickness was prepared as the mold of the specimen preparation. A speciment of 100 percent coconut fiber was also fabricated as comparison to the specimens were then tested with Tensile Test, Flexural Test, Compression Test, Moisture Absorption Test and Noise absorption Test. The best specimen was chosen for noise, heat and vibration insulator application.
