Thermal Performance of Kevlar Woven Fabrics Coated with Silica Aerogel

Popis výsledku v původním jazyce

Kevlar woven fabrics coated with aerogel particles were fabricated via blade coating. Fly ash nanoparticles were incorporated to investigate their effect on thermal performance. Thermal behavior of the prepared fabrics was evaluated and compared by using different techniques. It is found that the aerogels combined with a Kevlar fabric resulted in reduced thermal conductivity and higher thermal resistance. The fly ash coating brought a rapid rise in thermal absorptivity of the overall structure. Under laser radiation with high temperature, the aerogel content played 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 were 400-440°C lower than the uncoated fabric. The results also indicate 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.
