Within this study, monolithic three-dimensional silica aerogel (SA) composite parts with\nsuper insulating properties are presented. A generic part based on fiber-reinforced (FR) silica\naerogel for thermal insulation of the exhaust tubing system-to keep the exhaust gases as hot as\npossible to improve the efficiency of the catalyst system-was produced via a sol-gel-based molding\nprocess in combination with a supercritical drying using scCO2. A thermal conductivity of 16 mW\nm-1 K-1 was measured via a heat flow meter technique. In this manuscript, we present a full cycle of\nthe material compound design, starting with fundamental material evaluation including aerogel\noptimization, opacifier influence, and casting process. The obtained generic part in shape of a halfshell\nfor pipe insulation is characterized under real conditions.
