Abstract
This paper investigated the thermal properties of aerogel-coated Kevlar fabrics under both the ambient
temperature and high temperature with laser radiation. It is found that the aerogels combined with a Kevlar fabric contribute
to a higher thermal insulation value. Under laser radiation with high temperature, the aerogel content plays a vital role on
the surface temperature of the fabrics. At laser radiations with pixel time 330 μs, the surface temperatures of the aerogel
coated Kevlar fabrics are 400-440°C lower than that of the uncoated fabric. Results also show that the fabric temperature
is directly proportional to pixel time. It can be concluded that the Kevlar fabrics coated with silica aerogel provides better
thermal protection under high temperature.
