Abstract: Aerogel is a synthetic porous ultra-light material which is a solid with extremely low thermal conductivity, approximately 15 mW/m-K. Their low relative density (typically less than 5%) reduces conduction through the solid and their small pore size, typically less than one hundred nanometers, on the order of the mean free path of air, reduces conduction through the air as well as convection and radiation. On the other hand, Aramid fibers are a class of heat-resistant and strong synthetic fibers. Aramid honeycombs excel as ultra-lightweight material for structure reinforcement when good thermal and fire retardant are desired especially in case of building insulation. They are predominately used as a core in sandwiched structures to meet design requirements for highly stressed components. Aluminium honeycomb possesses the highest strength to weight ratio but due to its corrosive nature, it cannot be installed in the marine application and building insulation. Here we report on the hexagonal honeycomb structure of aramid fiber filled its core with silica aerogel to make it mechanical, corrosive as well as thermal resistant for building insulation or like other applications. The reported work has already done on the mechanical behavior of it here we will analyze its thermal behavior experimentally.
