Composite Materials of Sound Absorption Polyurethane Foam, Pineapple Fiber and Banana Fiber

Abstract

Research has been carried out on the sound absorption properties of sound-absorbing materials made from Pineapple Leaf Fiber, PUF, and Banana Trunk Fiber with the resin matrix. Absorbent in the ratio of 2:1, 1:1, and 1:2. The research method was carried out first by making samples by taking pineapple leaf fiber and banana fiber, and decomposing the alkaline treatment fiber with 4% NaOH for 4 hours. Rinse with aquades until clean then dry. Composite molding was carried out with a Hot Press for 240 seconds at a temperature of 1100C. Then the sound absorption test was carried out using a signal generator and sound level meter concerning the principle of the E-1050 impedance tube method, at a ratio of fiber: matrix 2:1 capable of absorbing sound at a frequency of 400 Hz at = 300 Hz.
