Study of Acoustic Properties of Chicken Feather Fibre (CFF) and Its Hybrid Composites

ABSTRACT

This study discusses the effect of molding temperature, molding pressure and molding time on the final compression molded CFF and its hybrid composites for its acoustic property. The results of tests like sound absorption coefficient, noise absorption coefficient (NRC) value, thickness and density of composites conducted to characterize the bio-composites developed with different fiber loads of chosen fiber and processing conditions, are discussed in this study. When comparing the overall results on the acoustic property of the composites, 100% CFF composite showed highest NRC of 0.6 by keeping the process variables at lower conditions (165°C temperature, 5 Bar pressure and 3-min time). The influence of temperature and pressure is significant on the NRC value than time on the acoustic properties of the composite board. If the fiber loading of CFF rise, the NRC value also increased. The maximum sound absorption observed at 1.8 KHz because of the natural frequency of the CFF material. The processing conditions, reinforcement fiber wt%, thickness and density have a significant impact on the NRC values.

摘要

研究了成型温度、成型压力和成型时间对最终压缩成型CFF及其复合材料声学性能的影响。本研究探讨了不同纤维负载及加工条件下生物复合材料之吸声系数、吸声系数、厚度及密度等测试结果. 在比较复合材料整体声学性能的结果时，100%CFF复合材料在低温（165°C温度、5 bar压力和3分钟时间）条件下，其NRC值最高，为0.6. 温度和压力对NRC值的影响比时间对材料声学性能的影响更大. 复合板如果CFF的纤维负荷增加，NRC值也会增加. 由于CFF材料的固有频率，在1.8kHz下观察到的最大吸声量。加工条件、增强纤维重量、厚度和密度对NRC值有显著影响.
