Abstract


Wood-plastic composites are a new group of materials that can be used in construction instead of wood and plastic. They are used in various industries due to features such as sound and water absorption, among others. This article aims to study the acoustic properties of wood-plastic composites made of wood flour, low-density polyethylene, and chalk. In this study, 6 combinations were made with different material percentages. Acoustic tests were performed for frequency ranges of 125, 250, 500, 1000, and 2000 Hz. The results of this study showed that the maximum amount of sound absorption was observed at a frequency of 2000 onwards. At the frequency of 25 to 2000, no remarkable change in sound absorption was recorded. At the 2000 to upper frequencies, one of the samples displayed the maximum amount of sound absorption. In terms of water absorption, a significant variation was reported in three samples with passing time (2, 24, 48 and 72 hours).
