Experiment Study on Sound Properties of Carbon Fiber Composite Material

Abstract

In this paper, the sound absorption coefficient and transmission loss of carbon fiber composite material are tested by stand wave tube equipment, and the factors affecting the performance of the carbon fiber composite material are analyzed. The results show that the sandwich structure can effectively improve the sound absorption coefficient and transmission loss; increasing material thickness appropriately can also improve acoustic performance of the carbon fiber composite material. The carbon fiber composite material with reasonable structure design can be used as acoustic material in the field of vibration and noise reduction.
