Abstract

Recently, the importance of GDI and diesel engine noise reduction is required, so newly designed components very close to noise sources are added in order to maximize the sound absorbing performances. In this study, the high temperature resistant part made with meta-Aramid nonwoven, which was applicable for high temperature applications of about $200^{\circ}C$ or more, such as engines and exhaust systems, was developed. And three-dimensional shaped component was successfully fabricated, and it was observed high temperature resistance of $260^{\circ}C$, lightweight properties and the noise was decreased by 1.0 dB with 70 g of product.
