Abstract

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.
