Abstract

The present study provides a comprehensive analysis of the use of basalt fiber as a multifunctional material for automotive mufflers. It has been proven by calculation that the optimal combination of fiber layering reduces noise by 8.2 dB in the range of 50-5000 Hz at a temperature of 700°C, which is 23% more efficient than traditional solutions. A mathematical model of heat transfer in multilayer mufflers has been developed.
