Abstract: Fiber glass has been widely used for automotive exhaust muffler to achieve good performance of noise reduction from the middle to the high frequency range. In this paper, the classification of the raw material and component of domestic fiber glass was studied experimentally. The results indicated that the domestic fiber glass can completely meet the requirements of acoustic attenuation performance.
