Infrared Thermal Imaging Analysis of Thermal Insulation Performance in SiO2 Aerogel Fabric

Abstract

This study investigates the thermal insulation performance of SiO2 aerogel fabric using infrared thermal imaging. Surface temperature and heat distribution were measured utilizing an infrared thermometer. The impact of various factors, including molding process, weight, and layers, on the fabric’s thermal insulation performance was systematically analyzed. The findings reveal that fabric produced through fiber mixing with aerogel powder exhibits superior thermal insulation properties compared to powder impregnation. Moreover, an increase in layers and weight corresponds to a reduction in surface temperature and an expansion in the area with lower temperatures. This effect indicates an enhancement in heat propagation range and an improvement in overall insulation performance.
