摘要
玻璃纤维被广泛应用于汽车排气消声器中以降低排气系统的中高频噪声。通过对某国产玻璃纤维进行原材料级别和零部件级别的实验验证研究,结果表明,国产玻璃纤维性能完全能达到消声性能要求,从而为进一步成功国产化奠定基础。
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.
